Edit: After clarification, your question might be reworded as: "Can a symlink name (or any Unix/Linux filename) contain a forward slash /
?"
The answer is: No. The forward slash /
is hard-wired at the file system level as a path separator, separating directories and their content.
But maybe this can help you:
In some cases, symlinks to directories are useful. The following existing path
/a/b/c/d
could be symlinked into /somewhere
$ ln -s /a /somewhere
so that /somewhere/a/b/c/d
becomes a valid filesystem path:
$ ls /somewhere/
a
$ ls /somewhere/a/
b
# ... etc
I think that's as close as you can get.
