A $6.61 "linux computer" that's about the size of an Arduino Pro Mini...

I stumbled across it on mouser:
https://www.mouser.com/ProductDetail/Seeed-Studio/102110199?qs=ahcBuItHZ3zN8FXDSjSZHQ%3D%3DAre there others like it? Seems like you could staple either it or a Raspberry Pi Zero onto an Arduino Pro Mini and then you'd have a very versatile all-in-one tool.

Check this one: http://linuxgizmos.com/linux-driven-sbc-costs-6-or-8-with-wifi/
It has betterl mainline linux support and the ARM core is newer and faster and has more RAM. -
Rock Pi S is 75% bigger (38*38mm) but still tiny and in a completely different league, it can do some RPI style work for 10$

As it turns out, there's at least one dual core SOC already on the market with one of the cores runing Liinux and the other core acting as an MCU: https://www.st.com/en/microcontrollers-microprocessors/stm32mp1-series.html?querycriteria=productId=SS2003

@nca78 At least in the past, the trouble I had with non-raspberry pi SBC's is that the linux software coverage for them was typically spotty/buggy. Has that improved at all, or is it still a big risk?

Things have improved a lot the last few years, as long as you are careful in device selection.
Don't become enamoured with hardware specs only. Some of these SBCs look great "on paper" but the software (driver) support is awful and they are stuck on some old kernel because the Chinese mfr. do not understand anything about what is Free Software and do not cooperate with the community in releasing documentation so we can write drivers, etc. Also look for good community support around the device in question. But typicaly this will be ~= the above (the more open the device, the more, better, and longer term support).
If you do a little homework though, you will be alright. Some good resources to get started are Armbian (stick to their Supported Devices list, and you will have a good result), https://www.fsf.org/resources/hw/single-board-computers, and linux-sunxi, etc...
