Yep. Whether or not you want to count it as a "stage" is up to you... or more importantly, how you connect it. Say you take NFB off the output; an extra coupling capacitor (to the CF) will give you trouble, however a cathode follower can be direct coupled easily, making an essentially invisible (electrically) buffer.

But that's an answer much too specific for such a vague question. I'd rather say something nonsensical like "battle of new orleans" in response. :D
