Yes it is:
Type: region
Subtag: VC

I know it's a long and heavyweight document, but I've tried to explain
this particular facet before. Let's try again.
Region subtags, per se, can ONLY come from two sources:
1. 2-letter code elements *officially assigned* in ISO 3166-1
2. 3-digit code elements in UN M.49
Code elements that were assigned in ISO 3166-1 at any time since 1988
are eligible to be subtags. Not all code elements from UN M.49 are
eligible, including those that duplicate ISO 3166-1 codes and those that
represent non-geographic collections. RFC 4645 (which is much shorter
than 4646) explains this in more detail.
Region subtags can NOT come from any other source. They cannot come
from ISO 3166-2 even though there are many 2-letter code elements in
that standard. They cannot be proposed by individuals, debated on the
list, approved by the Reviewer, etc. UNLESS they come from ISO 3166-1 or
UN M.49. That is pretty much all there is to it.
A language as used in "region X," where "region X" cannot be adequately
represented by a region subtag defined as above, can be covered by
proposing a variant subtag for region X. That is what Gabriel Babiano
has done for Valencian and it seems likely that the subtag "valencia"
will be approved. It could not be approved as a region subtag because
neither ISO 3166-1 nor UN M.49 has a code element for either Valencia
proper or Comunidad Valenciana.
