They can use plenty of things related to Gallifrey. To wit: the Great Houses. The anchoring of the thread. Looms. The caldera and entry-point of the Yssgaroth. The name 'the Homeworld'.

The fact that those things diverge and become "contradictory" has nothing to do with anything. The Eighth Doctor sure diverged quite a bit in the books compared to the audios compared to the comics, but unlike Big Finish themselves, we don't go raving about alternative timelines. We just report the facts, warts and all.

You speak of things having to be "under the same licensing or control", but, as pointed out at T:CANON, the beautiful thing is that in the DWU, ain't no such thing.
