To answer your question, no you cannot install BOTH Ceon URI and Ultimate. SEO together..
Minor correction, they can be "installed" with the intent of replacing one with the other. They can't both be fully installed for normal operation.

Besides why would one want to leave code behind that does not serve a functional purpose. There are instructions that indicate it is possible to convert from another URI rewriter to CEON URI Mappings by keeping the other rewriter active while transitioning to CEON URI Mappings.

I thought also that USU used .htaccess rules so there would more than likely end up being a conflict of some type anyways to have both fully setup at the same time.
