Does LU stock get allocated TOPS numbers when running on Network Rail infrastructure?

They will all have more and shorter cars than current trains do with all versions having the same sized cars, after all it is a “standardised” fleet. The only real difference (from a passenger point of view) is expected to be the number of cars per train set.
Likely this will also affect the number of spaces for wheelchairs, prams, luggage, and/or bicycles.

Possibly, there could be some variation in that, though were that to occure it'll simply be a byproduct of an extra or missing car, and in the same way will affect the number of spaces for sitting/standing passengers. Think how an S8 does not specifically have extra wheelchair spaces over an S7.

Also I thought that Central Line trans would have to have their shoe equipment in a slightly different positioning as their positive rail is higher up than on other lines?
positive shoe equipment is in the same place on all Tube Stock, the Central Line trains only requires this equipment to ride higher in the tunnel section because of the tunnel dimension. A new “L” style of positive conductor rail is being trialled which may negate the continued use of specialist equipment

With nine cars in the Piccadilly line's 105m variant (assuming comparable length to 1973 Tube Stock trains), there would be more than a single car's worth of difference in the Central line's 130m version.

I think it's likely that passenger layouts (with different vent locations, floor hatches, under-seat space, etc) will broadly match underfloor requirements (distribution throughout the unit of things like compressors, motored bogies, air conditioning equipment, etc), to minimise the number of different car designs — so the technical spec might well dictate how the train gets used by passengers.

I obviously don’t have the specific figures but I would suspect that as with any articulated train the end cars will be longer than the middle cars which may account for the discrepancy.

Was recently announced that Piccadilly 9-car would be 113.7m (over couplers) v. 107.1m (over couplers) for ‘73 Stock

As the 1972 tube stock is approximately 113.9 m long so the Piccadilly line train configuration can be used on the Bakerloo. The average length of each car on the 9-car train is 12.6 m but it is inevitable that the end cars will be longer than the intermediate cars, and it is far from certain that all the intermediate cars will be the same length; something not yet declared. I expect car lengths to be adjusted to produce an 11 car Central line train approximately 132 m long. It has to be an odd number of cars if the train is to be fully articulated.

any reason it has to be odd?, why would an even car formation not work?

Both of which new rolling Stock will be of 5-cars.
Articulation from end-to-end only produces odd numbers
There are plenty of examples of articulated train sets current and past that have had even number of coaches from Quad arts to FLIRTs (though yes I know the GA ones are not 100% articulated). I fail to see what logical reason there could be as to why an articulated train could not have an even number of vhiecles. https://www07.abb.com/images/librariesprovider140/default-album/image-header-flirt.jpg?sfvrsn=1
