Yes, this is absolutely possible. This works for Function-level analyses of course (e.g. ScopInfo), but also for Scop-level analyses. If the querying pass is itself a ScopPass, this Just Works. Any other pass type can access Scop-analyses through the ScopAnalysisManagerFunctionProxy, like this:

  /* ... */ run(Function &F, FunctionAnalysisManager &FAM) {
    Scop &S = /*...*/;
    auto &SAM = FAM.getResult<ScopAnalysisManagerFunctionProxy>(F).getManager();
    auto &IA = SAM.getResult<IslAstAnalysis>(S);
  }
