No, because excluding commercial users is a field-of-use restriction, and you're not FOSS if you only offer a license which imposes a field-of-use restriction. Which is fine! Just don't call it FOSS.
Furthermore, it's really hard to define what non-commercial actually means. Creative Commons spent something like a decade trying to scope a reasonable definition and eventually ended up essentially punting. With a few exceptions like (arguably) secondary public education use, pretty much any non-trivial use has some commercial component.
There is no semantic game, open source software is a term of art with a much more specific meaning than the source being available. If you find this draining then you can simply stop trying to misappropriate the term.
