Sure, I suppose. And I do have a separate computer for HA, because I consider it part of the house.in a way that is simply deserving of (cheap!) dedicated hardware. But most of my multi-os stuff happens with VMs these days. After I spent a few years successfully running Windows as my primary desktop OS, as a virtual machine (with its own dedicated CPU cores and accessories like GPU), the lines between separate computers and different operating systems permanently became very blurry to me.
