As a simple answer and depending on the OS Version, yes.
Perhaps some key questions should be:
"(a) How effective would this be"
"(b) Is it comparable to a Windows 2011 Server?"
For (a) and for mac clients, very good depending on your skill set. For PCs, not great IMHO. Although with some effort it's passable but don't expect any where near the functionality you see built-into a Windows Server.
As you can appreciate there are no simple answers to this as the subject is vast. Ultimately the platforms are not the same and trying to make them the same would be a mistake. Best to take them on their own merits and try and plan your support architecture accordingly.
