I've installed WoW from disc just once, on day 1. I've since run it from that install on Windows XP (a couple different installations), Windows 7 Beta (a little), and linux (two clean installations). It moved hard drives when I upgraded a couple of times.
You should have no trouble. In the event that you do, you may find it easier (if not faster) to download the client with your battle.net account rather than messing with the discs.
