Absolutely it will work!
I have a cluster of 10 RPis with my main server (running Fedora) as the cluster controller.
As long as what you're running on the nodes is the right architecture, it shouldn't matter what the architecture of the controller is.
One big caveat: Make sure all nodes (including the controller) are running the same version of SLURM, or at least compatible versions. I had no end of trouble until i pulled down the sources and compiled locally for my RPis and my server. Since then it's been smooth sailing.
Cheers!
