Yes, you can download the images using kermit, for instance.

Well, not as a root file system. You can boot into a small RAM disk
and set up a ppp link, though.

That depends on your hardware and software. Define "full embedded
application". With 4MB RAM you can get started. Depending on what you
need in the kernel (networking, for instance) this can become a little
bit tight quickly.
