While it's recommended, the question was whether installing new user space
rpms without updating the kernel is supported, and the answer is yes.  Red
Hat recently published this article to clear up confusion on this topic.

https://access.redhat.com/site/solutions/401413

Specifically ...

"Red Hat does not require a system to be entirely composed of packages from
a single minor release, but many regard the kernel
version<https://access.redhat.com/site/articles/3078>
 and the contents of /etc/redhat-release as two data points that assist in
labeling a minor release without deeper introspection into additional
userspace package updates. Others have stated that minor releases are just
hundreds of errata published on the same day and labeled as a release for
convenience.


   - For example, a system may have the kernel installed from Red Hat
   Enterprise Linux 6.1, but user space packages installed from Red Hat
   Enterprise Linux 6.2. This would still be considered fully supported."
