Yes, the hub is identical
Same 4x108 PCD and same 65.1 mm centre bore: wheels from Alfa Romeo Junior bolt on and centre on DS DS 6 without rings. You still need to check the offset and tyres, detailed below.

Wheel by wheel: offset and tyres
Each original wheel from Alfa Romeo Junior is compared with the one from DS DS 6 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 DS DS 6 (M12x1.25), 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.
