I used to maintain a Linux distribution called "OpenWM8650" (back in 2011 / 2012) which was specially aimed at the WM8650 and WM8505. It would run off the SD card. Which wasn't great, but the flash onboard support was horrible at best.
Maybe you can find some old information on it, on XDA because the website for the initial distribution is long gone.
Yes you can, it won't be great though.
