No, that’s GNU with the “not UNIX” recursive acronym. Linux was named by the guy who first hosted Linus’ OS and was an amalgamation of “Linus” and “UNIX” (“nix” was a popular suffix for platforms of that type back in those days so “Linux” was a play on the authors name in the style of that naming convention).

If I recall correctly, Linus originally wanted his OS to be called “Freenix” because he thought naming it after himself was a little vein.
