A configuration with a 3 year old SoC, lower end RAM setup and a very small disk (because Chrome OS is supposed to be stateless, unlike Android) might not provide a good environment to run Android in, especially if there's some overhead in having two display managers around that need to be coordinated. Also, there might be additional requirements for the GPU - all that map-Android-display-to-Wayland stuff that is used to get Android output into Chrome OS windows requires a bunch of capabilities that aren't necessarily efficiently implemented on older SoCs. Rendering to offscreen buffers is a feature that GPU designers provided and improved bit-by-bit and only with lots of market pressure. A couple hundred hours of work to bring the kernel forward (and test that it doesn't introduce regressions) for a feature that will only frustrate users (because it's there, just not practically usable) may not be a good investment.
