No, and there's nothing wrong with this.

Actually - I didn't read the article very carefully, so I may be completely wrong here - it looks like the OP uses a bit incorrect term. To me it looks like the word he wants is "applicative", and the opposition to it would be "concatenative" (see: http://evincarofautumn.blogspot.com/2012/02/why-concatenativ...).

"Imperative" is usually contrasted with "declarative" (and not with "functional", which TFA seems to suggest) and in practice most languages are imperative to some degree, even the ones which are said to be "declarative" are most often not purely so (but see Datalog).
