I think so, looking at the MTB 11 speed chart.
It's a new Croix de fer build with a GRX 1x11 drive train, and I need a 142x12 rear hub.
From what I can see, the GRX rear derailleur definitely works with the XT cassette.
le_james-
I don't have any GRX parts I'm afraid.
I can only confirm that the 11spd 11-42 MTB cassette works with the Ultegra 'shadow' RD (on my Mason without any extra Wolftooth stuff).
You need to use a spacer (1.8mm I think) if you're putting an 11spd MTB cassette onto a 11spd road freehub.

Yes, GRX derailleurs work with 11-speed XT cassettes. Make sure you add a 1.85mm spacer if you are using an 11-speed road hub.
hippy

You sure?
What are you trying to do in real world terms? Put an 11spd MTB cassette onto gravel hub or something?
