I enabled Google Now on my Moto X out of the box, BUT I do not think you would need Google Now enabled to use touchless control. Touchless control uses Google Voice Search. While voice search and Google Now are both built into the search app, they are different features. If I were you I'd repost this in the Moto X forum though, as you'll be more likely to get more responses and maybe someone who hasn't enabled Google Now will chime in.
