regulations. But you are unlikely to be bothered by staff even if your bag is larger. I usually keep mine close to the door opposite to the platform, moving it as required.
My modus operandi is to roll the bike on the platform up to the location where I'll have to board, remove the front wheel, drop the bike in a bag (flight bag or rinko) and (eventually) board.
