They can clear you if they want, but do you really want to accept the clearance? On a nice little aircraft like a Fokker 50 with minimal cross wind and a long runway it might be sensible but a given a crosswind, tailwind, a 100 seater jet or a short runway it might not be such a wise idea. But you also have to consider contamination of the taxiways. Will you be able to taxi to you stand? And finally, how will you depart?
