From the article this submission is linked to:

"The M Developer Preview includes an updated SDK with tools, system images for testing on the official Android emulator, and system images for testing on Nexus 5, Nexus 6, Nexus 9, and Nexus Player devices."

So, no.

I don't think they released the Android L previews for the the N4 either? Maybe someone can confirm.

They didn't, but by the time Android M comes out, the Nexus 4 will be approaching three years old.

As a Nexus 4 user, I'm not holding my breath (and my N4 isn't holding its charge).

But the actual release may support it, theres no way to know now
