Not from Lisp, no.

What's in setup-cygwin.el is about as good as you can get in Lisp.  A
better solution would be to add to file-symlink-p and
make-symbolic-link the ability to recognize and create Cygwin-style
symlink (and Windows 7 style symlink as well), but that requires
changes on the C level.
