Yes, though out of the box functional wayland, gpu acceleration, and pulse audio is new.
You're right, though, that the article is a bit awkward in not acknowledging that most people were already using VcXsrv or similar on the Windows side to run Linux gui apps.

the devil is in the details and the painful truth is none of that works real well. I am using JetBrains Projector instead which would be great if two super annoying bugs were fixed. Meaning that doesn't work well either -- for now. Maybe it will, maybe X+VNC will someday be great in a Windows VM -- but I have much larger confidence in Microsoft driving this to greatness.
