Yes, the hub is identical
Same 5x112 PCD and same 66.5 mm centre bore: wheels from Audi Allroad bolt on and centre on BMW 6 Serie G32 without rings. You still need to check the offset and tyres, detailed below.

Wheel by wheel: offset and tyres
Each original wheel from Audi Allroad is compared with the one from BMW 6 Serie G32 of the same diameter: how much closer the wheel gets to the shock absorber or how far it sticks out of the wheel arch, and whether the tyre keeps the same overall diameter.

Before fitting the wheels
An identical hub is not enough: offset, width and diameter change the position of the wheel, and larger calipers can touch a smaller wheel. Original wheels often use bolts or nuts with a specific seat: keep the fixings intended for the wheel, with the thread of BMW 6 Serie G32 (Ecrous - 14x1.25), tightened to the torque shown on its vehicle page. Finally, check that the size is among the approved fitments for your vehicle. This comparison is for guidance only: have the fitting approved by a professional.
