In theory, yes. In practice, it works fine. I've been running win 11 for my gaming needs on an even older Xeon (sandy bridge, so 4th gen, IIRC - the first one with pcie 3) with no issues. It has no TPM at all. I've updated it to 22h2 the other day. Works like a charm, and I almost enjoy using the latest update. I find it much less annoying than win10. In particular, the animations feel quicker. Regular updates are showing up and installing through windows update. For the upgrade to 22h2 I had to make a usb stick with rufus (tick "disable win11 checks" or similar) and run the upgrade from there.
