First, to answer the question asked: you can use them physically, but the shifting performance will suffer.
Second, there is no limitation on the wheel, for a campy 8 speed hub. Put a 10 speed campy group on the bike. 8/9/10 speed are all the same, unless you truly have a freewheel, as opposed to a cassette. For 8 speed campy, that is fairly unlikely, but I'm not looking at your bike.
If you don't have the option to run a new group without new wheels because of the freewheel, then my experience is that running an 8 or 9 speed drivetrain with a 10 speed chain ring set will produce slow and noisy shifting on the front chain rings, when shifting up to the larger ring, and pretty normal shifting when moving from large to small rings. It will also rub on the small chain ring, when in the bottom 2 or 3 cogs in the rear.
