No, but for any available certification there are two pieces -
distro and application certification.  The CGL-ceritfied distro
is a subset, so a CGL-certifie app would by definition also work 
on a full LSB system.  Meanwhile, a full-LSB-certified app would
probably include libraries that are not part of the CGL profile,
and thus would likely not work on a CGL system. I think that's all
anyone was saying.

And this is the thing that is worrying some people: once you start
segmenting the certifications, you have to start worrying about
matching the right things together, and understanding the above
matrix.  I don't think this is a particularly severe problem in
these controlled cases.
