Yes, but unfortunately for us the -A flag was added to POSIX Issue 7.
It's not present in the previous version of POSIX, Issue 6:
http://pubs.opengroup.org/onlinepubs/009695399/utilities/ls.html
It came from the BSD world, so it might not be available on older
SysV-derived systems (AIX, HP-UX, even Solaris... I don't have access to
these anymore so I can't say). Ultimately it's probably more portable
to assume "ls -a" always prints "." and ".." than to assume "ls -A" is
supported.
Cheers!
