The Windows Subsystem for Linux is now open source
(blogs.windows.com)
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

It's a Linux subsystem for Windows. As in, you run Windows and within it run Linux. Thus Linux is the sub-system, while Windows is the "overarching" system. Therefore, it's Linux running as a subsystem on a Windows machine. Therefore, a Linux subsystem on/for Windows.
<edit>
That was just setting the two viewpoints equal.
Now, to add why this one is more "correct": when talking about Windows (or Linux or anything else fir that matter) subsystems, you don't call the Windows file system the Windows subsystem for Files or the Windows subsystem for Networking or Linux subsystem for RNG - You call them the filesystem, the networking system or the RNG system. And since none of them get the "for host" suffix, it seems natural to assume it's the guest system that's the "sub" system, with the other one being the whole.
