Of course, another thing to keep in mind, that I didn't remember to mention in my first reply, is that some applications may be sensitive to the patch-level of either Windows or SQL Server, on the server they live on. If different applications require different patch levels, then they have to be on different servers (or different VMs), or you can end up violating support contracts.
