Almost impossible.
There are 2 types of links.
One will give you a indication that its a link by seeing the end of ls -l
a -> b
The other one will have same inode no.
For this you will have to search the filesystem to see if any other file has the same inode no. or not.

matchpathcon_filespec_eval
matchpathcon_checkmatches(3) SELinux API documentation matchpathcon_checkmatches(3)
NAME
matchpathcon_checkmatches, matchpathcon_filespec_add, matchpathcon_filespec_destroy, matchpathcon_filespec_eval - check and report whether
any specification index has no matches with any inode. Maintenance and statistics on inode associations
SYNOPSIS
#include <selinux/selinux.h>
void matchpathcon_checkmatches(char *str);
int matchpathcon_filespec_add(ino_t ino, int specind, const char *file);
void matchpathcon_filespec_destroy(void);
void matchpathcon_filespec_eval(void);
DESCRIPTION
matchpathcon_checkmatches() checks whether any specification has no matches and reports them. The str argument is used as a prefix for any
warning messages.
matchpathcon_filespec_add() maintains an association between an inode ino and a specification index specind, and checks whether a conflict-
ing specification is already associated with the same inode (e.g. due to multiple hard links). If so, then it uses the latter of the two
specifications based on their order in the file context configuration. Returns the specification index used or -1 on error.
matchpathcon_filespec_destroy() destroys any inode associations that have been added, e.g. to restart for a new filesystem.
matchpathcon_filespec_eval() displays statistics on the hash table usage for the inode associations.
RETURN VALUE
Returns zero on success or -1 otherwise.
