This is what I was going to suggest, or some Linux equivalent on a thumb drive. (Forget Windows.) You would basically mount the PC-on-a-drive, as has been done since forever by those chasing portability. :)

Since this necro-thread was resurrected and I have mumbled something in it already, my new work laptop (Dell Precision 3530) has the capability to charge through the USB-C, and it is quite nice when you have a "docking station" like Dell WD15, which I have at work.

Through that small WD15 box, the laptop not only charges, but get its (fixed-line) internet connection, support for two external monitors, extra USB ports and blaa blaa blaa. So basically the same as with more traditional laptop docking stations but the docking station itself is just a small box and you connect your laptop to it with one USB-C cable.

Neat and tidy. Now the traditional docking stations seem quite clunky to me.

Good thing, too. Curious why you'd want to? I like that idea, too, until i discovered better ways for what i wanted (portable machine that I could code and optimize for). I actually got a specific version of a TI-nSpire just to do that, and ended up never using the version specific stuff. Alot of phones and tablets now have nice emulators for specific processors, too. And if you use android, termux is your friend. I can actually code for my arduino in assembly and "compile" and upload via my OTG-supporing tablet.
