No. The OS OpenData licence also requires "The same attribution
statements must be contained in any sub-licences of the Information
that you grant, together with a requirement that any further
sub-licences do the same."

Which I interpret to mean that not only must OSM provide that
attribution, we must ensure that all derived works, and any works
derived from them must too. In which case, *just* providing
attribution on the OSM website isn't, in itself, sufficient.
