One can know the name Luke Skywalker without ever having seen any of the movies. I unfortunately know who Edward the Vampire is despite never having seen a Twilight movie or read any of the books.
Yes, one can - but since O'Neill is into SF which was stated in some episode (don't know which now), I'd wager he'd seen SW.
I don't remember it being stated O'Neill was into sci-fi. Indeed, the Star Wars conversation in Ascension seems to indicate he isn't (Carter: "You've never seen Star Wars?" O'Neill: "Well, you know me and sci-fi.")
Of course, over the course of the series, O'Neill makes a few Star Trek references indicating he might have more than a passing interest in Trek.
