I mean… not quite. “linux”, properly, refers to the kernel. Android runs using linux as its base hardware interface. On its own it’ll just sit there, handling low-level IO and managing memory and whatever else was compiled in.
There are some GNU bits and pieces between the kernel and android, but it’s very much not a GNU/Linux system. “Linux” in the sense of “getting linux to run on things”, generally means “linux and at least a barebones GNU install”.
It’s a pedantic distinction, but distinctions are important in tech.
