Whether it is right depends on why you want to do it.
The fact that you have to ask implies your reasons aren't sound and you would be better off using a more beginner friendly distribution, such as Ubuntu.
If you have a solid reason to want to learn specifically redhat and novell, rather than generally Linux, you might be best off starting with openSuse
Much of what you might learn with Ubuntu is different from what you could later apply to using Redhat or Novell Linux. But almost everything you would learn starting with OpenSuse applies to Novell Linux and more of it (compared to Ubuntu) matches Redhat.
I think there is better beginner support available if you start with Ubuntu, and most of Linux is the same across all distributions. So the benefits of starting with Ubuntu might still apply even if the goal is learning Redhat and Novell.
If the goal is to learn Linux for an IT job, then Redhat and Novell are important to learn, but that still doesn't mean the best path is trying either of them early on. On that path, the second distribution you learn (after starting with either OpenSuse or some beginner friendly distribution) should be Centos. Centos lets you learn everything you need to know about RHEL (Redhat Enterprise Linux) without paying for a license or being constrained by the license (practice installs and other experiments are much easier when no license is involved).
