While it is not officially supported there is nothing except your own know-how of linux which would prevent you from installing it on CentOS. CentOS is also very similar to RHEL, from a high level they are virtually identical minus brand/logo and support. Pay strict attention to the system requirements for RHEL described by SAS and you should get up and running. As far as installing SAS software on unsorted operating systems is concerned though, that is going to be your burden as a result.

For more information there's a SAS Support for Alternative Operating Systems page on the SAS support site.
I haven't yet personally encountered any issues that I haven't been able to overcome when running SAS on other Linux distributions including CrunchBang, Arch, Ubuntu, and Debian. However, when I did those installs it was on the basis that they were unsupported and that if I did need to talk to SAS technical support then I might need to replicate any issues in a supported operating system. That wasn't a big deal for me because those installs were done for testing purposes only. For SAS installations where lots of people would be relying on the platform I'd find it much harder to justify the use of an unsupported operating system. In those situations it could be impractical and costly (in both time and effort) to potentially have to replicate a SAS platform issue on a supported operating system (especially for the more complex SAS platform installations). In that case why not use a supported operating system in the first place? If the operating system choice was based purely on the cost of the supported operating system then I would say that the cost of having to support an unsupported platform could end up being higher that the cost of the supported platform itself.
