An OEM would certainly tell you yes, but they factor in all the worst case, yet reasonable maneuvers; like 90% jounce (well into the jounce bumper), full outer turn, 80% bushing compliance, grown tire, with body and chassis build tolerance going in the worst-case direction...
Despite that kind of conservatism, I agree with their stance. I wouldn't use a wider tire. I'm not even sure that's an advantage when it comes to snow and ice traction.
Just realized this: That would be much too large in the OD also! A full inch larger OD. That, combined with the width and the same offset would certainly cause tire-to-body contact.
This doesn't even address the tire pressure monitoring system thread (that's been already mentioned in this thread).
