Was this preinstalled? If so, no. It is licensed for that original hardware.
If not preinstalled...as in you bought it and you installed it, you can probably install that on a different device. In this case a VM within the Mac system.
But that invalidates the install on your original desktop. Rendering it useless until you install another OS.
To your basic question...either way, no, not really.
One license, one PC.
