Absolutely. I'm involved in systems design & IT strategy for a very large institution. By and large we've found literally zero advantages imparted to end users by Windows 10, besides being forced to deply it by MS deciding to early end-of-life Win7. Some cool features in Server 2016, but nothing that will affect a user's workflow in the slightest.
I was a bit of a Windows 7 stalwart until recently. I upgraded my parents' Vista machine to Windows 7 ... very sluggish. Thought I really needed to get them an SSD at some point. Then I upgraded it to Windows 10 on a whim - incredibly snappy. No need for SSD yet.
Sure, snappier on older hardware is a plus. But we've got a 4 year replacement cycle, and a slight increase in snappiness isn't what I'd call a major upgrade.
