Lighthouse based controllers can be synced with some effort with any headset. But other way around - not. Camera based tracking headsets have custom algorithms to track their own controllers, so no, Oculus can no't track WMR controllers and vice versa.

But you can use Valve Index controllers with any headset in SteamVR, but you need to buy lighthouses, and use OpenVR Space Calibrator to align tracking spaces.
