Yes, they list the advice in the article as applying to NT 4.0. And the advice on access controls does apply there.

But the only sentences stating that specific versions have actually received C2 type certifications are in the summary. And the statement there is that 3.5 was certified as of 1995 in the USA, and 3.5.1 was given a E3/F-C2 rating in the UK. Nowhere in that article does it say that any version of 4.0 ever received C2 certification.
