I think the tricky thing here is that what used to be called a microcomputer (or apparently a home computer, though that's new to me) is kind of making a comeback (with things like the Pi 400 and some various efforts at building new all-but-the-screen-in-one portable-ish computers in the image of the c64 or spectrum or appleII) and they really ought to be distinguished from what we now call a PC (or laptop, for that matter). But it would be confusing to repurpose minicomputer for it, given that microcomputer is a term still used to some extent, and is more present in most people's memory.
