[Star Wars] Can't Jedi use the force to turn the other Jedi's light saber off?

Seriously.

They could, but without knowing the mechanics of the lightsaber in question, it's not as easy as flipping a switch. Remember, each lightsaber is custom made, and while they follow similar design patterns, the ignition may be dictated by different mechanisms, such as an activation stud, or perhaps an internally switch that can only be reached with the Force.

Additionally, most Jedi and Sith learn early on to protect themselves from Force attacks with resistance methods. Only by wearing down the Force-user, breaking their concentration, punish a moment of relapse, or completely overwhelming their defenses would you be able to attack the Force-user with Force based attacks.

And even if you do just flick their lightsaber off, it's just as easy as flicking it back on. You might as well take the time to directly attack the person rather than disarm them for a split-second.
