Technically, you can do as you describe. However, be prepared for an assortment of cleanup tasks. If your system has been around for a while you've made use of that server name in a number of different areas. You potentially could cut off some users or some applications from your server. Also, software installs could potentially have used the server name. Depending on the number of machines in your network, I would take a close look at EVERYONE's installed applications to see if there's any impact.
