Hardware can stop you from installing some operating system onto the computer itself, but it can't stop you from installing it onto a virtual machine. From the hardware's perspective and the operating system perspective, a virtual machine is yet another program, hardware has no way of knowing there is another operating system running in it.
Though, in the modern versions of Windows Virtual PC, Windows 98 will, as far as I am aware of, fail to boot in GUI mode, I have only managed to have them run in MS-DOS mode. There is probably no configuration that is compatible with all the OS-es people will try to install on a virtual machine, like both Windows 7 and Windows 98.
