Most font collections include the right to use them für print and PDF, but not for EPUB. But I do have some fonts I'm allowed to use in my ebooks – and "America Typewriter" happens to be one of them. What also works is "Courier Prime". Both look okay (but not always perfect) on different e-readers I tried.

BTW I found out that there can also be a difference between different readers with 800x600 resolution. The old Kindles seem to use a different font rendering method than e.g. the Tolinos. On Kindle everything looks sharper, but with some fonts also less smooth (what makes using alternative fonts more difficult). The Kindle 800x600-devices work best with the built-in Caecilia font (easier to read than Bookerly on the higher resolution Kindles, if you ask me). And of courese there are different font sizes which make a difference, too. Very hard to find a font to embed that works everywhere, so embedding will never be my first choice.
Another example is that the old Sony Readers at 800x600 had a rather good font rendering engine but the nook STR has a terrible font rendering engine. Same screens, but you'd think they were two different fonts.

One o the problems is that Mobi has no embedded fonts so whatever you embed for your typewriter will not work. You'd need to do something like monospace or san-serif. But By default, Kobo doesn't work with monospace unless a font named courier is installed in the fonts directory.

Some programs such as Marvin (for iOS) don't work with embedded fonts when set to allow overrides. I've tried to get the author to fix this, but he didn't and now Marvin is abandonware.

There is no solution where embedded fonts will work in all cases. So don't do it if you don't have to.
