I mean, maybe I’m gonna sound like that weird copypasta, but when people say Linux they mean GNU/Linux and stuff inspired by it, like Alpine. On desktop also X11 or Wayland and the usual set of tools.

Android is neither of that, so no, when you say Android is Linux, you’re wrong, because you’re ignoring what people mean by saying something is Linux.

If you truly want to mention Linux with Android, you can say that Android uses a Linux kernel (heavily modified, one might add).
