I think the real determinant is "Do we want the dice to fall where they may as an absolute?" If so, then yes Luck is inappropriate. So are some of the other mechanics that mess with dice rolls, as are rules that mess with dice rolls. This would also preclude the GM fudging rolls, though to be fair it wouldn't be a problem because - when committed to going with the dice results and nothing else - you're not rolling unless all possible outcomes work for the story and the player's sense of fun.

I've not played in any hard-nosed, realistic adventures, but I can certainly see them lending themselves more to strictly following the dice than a more lighthearted game. On the other hand, someone is free to have a gritty, realistic setting where "Luck" is fine because some folks realistically have it when you view their lives in hindsight. That person may have simply rolled well each time or may have instead used Luck to try and skew things in his or her favor. If "Let the dice fall where they may!" is the driving force of the game, then even a fanciful or silly setting still ought to disallow Luck.
