You could do that, they will test whether the wheels run a minimal
case in terms of versions and dependencies.  You may hit
inconveniences building packages, because the toolchains are rather
old.

Alternatively you could use a bare but more recent distribution.  For
example, my multibuild framework for manylinux testing uses manylinux
containers to build with, and bare Ubuntu Trusty images for testing:
