If you brought it closer to geosync, you would actually have to spin it up a little bit faster to keep it tidally locked. But even then, if you hooked a cable to it, the cable would still wrap around the earth because the earth is still spinning, which would pull the moon closer and either make it crash into the earth if the cable was strong enough, or it would more likely fling it off into the solar system where either another planet would take it for itself, or it would most likely come falling back to earth's neighborhood like the biggest shooting star you'd ever see.
What you need to do is stop the earth from spinning to keep the cable from wrapping around the planet, but then geosync gets really far away and you have to use a lot more cable. It's probably easier to just communicate with the moon using radio waves like we already do.
