I don't think you could offend anyone by being correct. In theory, if the aircrafts wheels were frictionless then the conveyor would have absolutly no affect on the planes ability to run up the runway and take off (Inertia would keep the aircraft still (with engines off) regardless of conveyor speed). I was assuming in this case that the wheels did have friction and thus the conveyor would be able to exert force on the aircraft. Is the question asking whether or not the aircraft could take of standing still (conveyor speed increasing to keep the aircraft still)? or if the aircraft could take off with the conveyor matching the wheel speed (obviously yes, but in its regular distance)?
