No, because the Agile Manifesto isn't a slogan for a concrete methodology, it is the explanation of a set of values.
The concrete methodologies come from different sources than (and post-date) the Manifesto; the Manifesto wasn't written to sell them.
It's true that there is a mismatch between the values articulated in the Agile Manifesto and the concrete methodologies that bill themselves as “Agile”, but that's not due to the Manifesto being a dishonest sales pitch for the methodologies, it's because the methodologies are dishonestly appropriating the label associated with the Manifesto.
