Technically memfd_create will let you create a file descriptor backed by a memory region. However in Linux I don't believe there's a way to dlopen that. (Maybe dlopen /dev/fd/... might work?) In FreeBSD there's a fdlopen library function.

Edit: glibc proposal which was never accepted: https://sourceware.org/bugzilla/show_bug.cgi?id=11767
