I think it is true to say that it is possible to 'roll' any aircraft.
Because if done properly, there should be no more than a very slight
extra
strain on the airframe.

Depends on the kind of roll. But yes, it is theoretically possible to
maintain low G forces throughout an entire roll. Witness the 707
prototype
that was rolled over Lake Washington back in the 60's.

Not all rolls have this characteristic though.

Exactly. You're not going to aileron roll any large civil aircraft but
barrel rolls...possibly.
