yup, you can do age_mover status
it will just cat out the pid file.
/var/run/mover.pid
I also write the status of the current mover of what file it's on and there is a "GUI" update, if your willing to modify unraid from stock files. (manual install, I'm out the next few days so can't provide instructions right now, but they are posted here or on Reddit if you want to hunt them down)
