Most of what you said is exactly my point. It’s true the word Linux, used properly, refers to a kernel and not an operating system. But that’s not the way the word is used in practice, and it is not what OP meant when they used it. They meant " an OS with the Linux kernel and GNU userspace utilities." When the word Linux is used that way, Android is not Linux.
Do you not consider Alpine Linux to fall into the general category of “Linux”, then? It lacks GNU user space utilities, though there is never a world where I would not consider it a “Linux” operating system. You seem to be overgeneralizing here and making assumptions about OP’s intentions that aren’t based in fact. I don’t see the point in drawing meaningless lines, here. What you’re referring to (as described by the GNU project) is GNU/Linux, not “Linux” by itself. The two are often but not always used interchangeably, and treating them as exactly the same leads to major outliers, like Alpine. I’ve heard plenty of people use the term “Linux” in practice to describe software running on embedded devices that don’t contain GNU utilities, so this isn’t exclusive to Alpine. In fact, the only real exception that I see consistently to operating systems that run the Linux kernel is Android, so it makes much more sense to formulate a description of the generic term “Linux” as simply having an exception for Android, though I’d argue that the only reasons that Android isn’t viewed as “Linux” is because it is a mobile operating system, it is developed with the sole intention of including non-free, proprietary software (AOSP by itself isn’t meant to be the full operating system on any device, but rather a framework), and the fact that the structure of the filesystem and the way apps are run differ completely from the ways of traditional “Linux”. It seems to be an exception purely by the fact that it operates in fundamentally different ways than other “Linux” operating systems.
Idk (I’m not op) but I think when people say “can I install Linux on this” everyone knows they mean gnu/Linux. Yes, if I’m picking a container base image obviously alpine is also Linux, and if we’re talking about kernels then Android is too. But if we’re talking about desktop OSes then I think it’s close enough.
GNU/Linux != Linux
Linux is a kernel
GNU/Linux is the GNU userland (tools and libraries) combined with the Linux kernel to form a complete operating system
Android is Linux but not GNU. So are Alpine, postmarketOS, and others I can’t think of
Linux is to an operating system as bread is to a sandwich… an essential component, but a slice of bread by itself does not make a sandwich make
I feel like that’s precisely the point they tried to make
