Memtest86 is a stand-alone program that does not require or use any operating system for execution. The version of Windows or Linux being used is irrelevant for execution. However, you must use Windows or Linux to create a bootable CD, Floppy or USB key. The Windows and Linux packages are identical except for the installation methods.
