Yep. Used the term since obtaining used networking hardware for learning. Then some super power-hungry Xeon rack servers. Now I loosely use it to refer to home-stored anything used for learning, fiddling, researching: old laptop which acts as a temporary Kubernetes node, Arduino clones or raspis doing various home automation stuff (even untouched for a long time, t's always work in progress in my mind, so "lab" applies) and some equipment used for hobbies unrelated to CS but very much laboratory-like. It's a fine term.
