A primary language subtag would be appropriate if and only if ISO 639 had already rejected assigning a code to Neo. Until/unless that happens, it is probably inappropriate to register any code for the language in question. And then, as Kent Karlsson points out, a 5-8 character primary language subtag would be appropriate. Section 3.6 of RFC 5646 spells this out:

    Subtags MUST NOT be registered for languages
      defined by codes that exist in ISO 639-1, ISO 639-2, or ISO 639-3;
      that are under consideration by the ISO 639 registration
      authorities; or that have never been attempted for registration
      with those authorities.  If ISO 639 has previously rejected a
      language for registration, it is reasonable to assume that there
      must be additional, very compelling evidence of need before it
      will be registered as a primary language subtag in the IANA
      registry (to the extent that it is very unlikely that any subtags
      will be registered of this type).

Internationalization is not a feature.
It is an architecture.
