Google is preparing to let you run Linux apps on Android, just like Chrome OS

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.

That's a bad move of Google, this has no reason at all!
Chroot/docker will use a more practical way to run Linux, as Android is just a Linux distro, why bother with running a whole another kernel!
A reasonable build of the kernel optimized for virtualization won't take more than a few tens of megabytes of RAM (and it will have support for memory ballooning, so the virtualized kernel will give the memory it doesn't need back to the host), and the userspace will need to be separate anyway due to how different Android is to normal Linux distros.
Containers are nice when you want to run dozens of separate services on the same server or want to get the benefits of infrastructure as code, but in this case they would provide minimal benefits at the cost of having no way of loading any kernel modules not built into whatever ancient kernel version your SoC manufacturer decided you have to use on your phone. Also, container escape vulnerabilities are still a bit more common than full VM escape, so this is also good for security on top of being more useful.
