directly on raw hardware, probably not.

I bet that there's a chance I could fire up VirtualBox and get IBM PC DOS or MS DOS running.

Many times, the function that either emulation, or virtualization serves, is to keep older versions of software running.

Your main question will the latest product not be able to run older
versions of the OS? True. There is LIC or Licensed Internal Code, that
has been updated for newer hardware. And they won't cobble old code to
support old hardware into newer releases. You can't run Windows 10 on a
dual diskette PC. You can't run DOS 1.0 on the latest laptops.
