Yes, if you draw a line on a map between Morgantown and Provo you come up with a greater distance.

But that's not how travel works in the 21st century.

I'm pretty confident that it would take less time for WV to get to BYU's campus than it takes them to get to some of the other B12 campuses. And there's no doubt that many if not most of the other B12 schools can get from their own campus to BYU's campus faster than they can get to Morgantown.
