YES, it can happen. The truck's Stability Control includes trailer sway control. If the truck detects unintended yaw, it will brake individual wheels to counteract that.
The O.P. asked if the
trailer brake controller can activate truck brakes. The correct answer is "no".
And it's a stretch to call truck stability control "trailer sway control". It will do nothing to counteract trailer sway, only attempt to solve whatever difficulty the truck is experiencing as a result of it.
Absent mechanical sway bars etc., the trailer itself will continue to sway unless its own brakes are activated to stop it, which the truck's stability system can't do.
