You are confusing between retail and OEM licenses.
Pre-installed Windows 7 machines are OEM activated which means activation is achieved through a combination of elements, some of which are specific to that particular OEM, at the factory.
Assuming for a moment that this can be replicated by the end user, the OP's Vista machine would need to satisfy 2 criteria. One, it would have to be the same OEM brand as the Windows 7 machine. And two, it would have to have a Windows 7 compliant bios.
Feel free to ask.
