Linux is a kernel. Embedded, server and mobile Linux distributions without glibc, gcc, GNU coreutils, systemd, D-Bus, Wayland, Pipewire, etc. are Linux too. Linux is not a specific desktop software stack that's largely used on FreeBSD and elsewhere too. Android Open Source Project and GrapheneOS are Linux distributions.
