To be fair, Tyrannical is merely suggesting that relevant experiments can disprove a particular hypothesis, namely that any god that happens to exist interferes directly in natural processes. This doesn't address the existence question directly. If it can be shown that some hitherto unexplained interference is taking place with testable natural processes, then the question arises, "what is the nature of this interference?" I suspect that most scientists will look for another testable natural process as the source of the interference, though, and if they alight upon one, we're back to square one. In order to establish that said interference, if it exists, is due to something other than a testable natural process, then one would have to rule out all testable natural processes - hardly a trivial task. Which again leaves IDists with a major problem. This, once again, leads to the inexorable conclusion that providing supporting evidence for a magic supernatural entity is a non-trivial problem of Nobel winning difficulty.
