People denied tenure in CS at Harvard have gotten senior (tenured) jobs elsewhere, but not in my opinion at places anywhere near as good.

You and I may have different views of what "anywhere near as good" means, so it's hard for me to accept your judgement at face value.

A difference is that people denied tenure at Harvard have gotten senior (tenured) jobs elsewhere.

My subjective sense is that there are only a few schools where denial of tenure isn't the end of the line for research professorial dreams.

OP's notion of the 7-year postdoc is an interesting one.
