Doubt it. Alexander was shown to be in a mountain/hilly area, nowhere near a lake.

He is literally standing in a lake though....

But what I think Terrini meant is that like the Keeper of the Lake (which we could see, but not access), Alexander might turn up in an area we already know. Though I agree with Enkidoh that he will likely turn up in a new area from the expansion.
