64MB used to be a lot of memory even for Linux. It is fine unless you're trying to run very bloaty software like web browsers. I wrote a fairly substantial embedded app for a 64MB ARM board running some forerunner of Angstrom Linux, in CPython, that used around 20 threads to talk to different peripherals. It wasn't terribly short on memory. It felt like a mini server. It ran Emacs just fine, and Emacs was once jokingly called "Eight Megabytes And Constantly Swapping" because 8MB was in those days huge. 64MB leaves plenty of space for it. The Raspberry Pi W is overpowered because it's basically a media processor. It's not for what we usually think of as embedded apps. The difference between the Linux and RTOS versions of this Pine board seems to be the amount of on-board flash. But given the built-in MicroSD slot, maybe that doesn't matter and you can run Linux on both.
