No way. You won't explode the tires or anything, but you'll have to run them at high pressures, the ride suffers, the handling takes a dump, the bike will be skittish and if you hit a patch of sand, the first thing that touches the ground will be your face. Grant Petersen at Rivendell has a tire-size chart based on weight, and while I don't have it handy, I think he'd put you on 28s or 32s at 80-95 psi.
