ISTR there's something saying ICANN would not delegate two-character TLDs unless it was for a code on the ISO3166 list and that TLD was then delegated to the appropriate authority in that new member of the UN. Can't be bothered to go look for that statement...

Since ICANN policies are subject to change it would be prudent not to rely on its TLD policies to decide whether a string is or isn't safe for private use. For some definition of "safe".
