Yeah, you definitely can. With naps, you may notice stronger sensations (especially you had lack of sleep frequently) or nothing at all, since you'll drift into sleep a bit faster before being aware. I had moments in naps where the desire to sleep was so strong, I ended up getting into a dream like state quickly and was lucid for a good bit. But ultimately, how you become lucid during naps is just as varied as attempting them during longer sleep periods and periods after a WBTB is performed.
