Hi Dan,
I am running PFE on a Windows 10 computer (without any problems) while the JEOL is still on Windows 7. No communication problems whatsoever, so you should be good based on my experience.
I only had twice problems with the enforced Windows10 updates already, this time it killed my 5 WDS input and I haven't figured out yet how to get it back. So I would have a mirror of your system as a backup in any case.
