Not according to the OSI definition, which arguably traces back very directly to the original idea behind the term:
> 6. No Discrimination Against Fields of Endeavor
The license must not restrict anyone from making use of the program in a specific field of endeavor. For example, it may not restrict the program from being used in a business, or from being used for genetic research.
The whole OSI endeavour is far from uncontroversial in the OSS/FOSS world. It's not gospel to quote from, particularly when it comes to commercial use. A lot of people would say that OSI exists precisely to make sure corporation-friendly clauses like this would prevail in the open-source world. Hell, the whole "open source" term was literally invented by people like ESR to differentiate from Free Software enough to make it an easier sell in the commercial world.

If it was invented for that purpose, isn't that a reason why one shouldn't use the term for things that conflict with that goal?
"Free Software" following GNU also can't have a non-commerce clause (Freedom 0). I totally get that people want to restrict commercial use, but I believe "everyone can use the software" is enough of a core value and a NC-license would be incompatible with so much of the ecosystem that it's fair to classify NC-licenses as something else.
