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?
It's times like this I'm pleased to be flying rotary wing A/C.
