Yes, the hub is identical
Same 5x108 PCD and same 65.1 mm centre bore: wheels from Volvo V70R bolt on and centre on DS DS 7 without rings. You still need to check the offset and tyres, detailed below.
≈: width estimated from the original tyre size.
Wheel by wheel: offset and tyres
Each original wheel from Volvo V70R is compared with the one from DS DS 7 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.

≈6.5Jx17 ET46 · 205/50R17 — Fits like the original
Compared with the original ≈7Jx17 ET44 on DS DS 7: shock absorber side −4.3 mm, wheel arch side −8.3 mm, tyre diameter −10.5 % : fit it with the original tyre size of DS DS 7 (215/65R17), not that of Volvo V70R.

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 7 (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.
