Hi Chris,

that's a prettty good question that I thought I knew, until it was pointed out to me that we (apparently) seem to dream in other cycles of sleep, not just during REM. The dreams are, however, not easily remembered at all (and probably nowhere near as intense or linear).

So, in my opinion, probably not. HOWEVER....

I would suspect that if you had good training in meditation - the kind which you can control your brainwave frequency pretty moderately, you should be able to have and experience very similar to LDing, if not LDing itself.
