There may be an issue with running a "brain" program on a non-brain hardware depending on what the program is. We don't know what the program is so it's hard to speculate but, it is possible that brain program is not well fitted to silicon based architectures. It may turn out that low-level physical and chemical processes that are crucial to brain functioning are prohibitively expensive to simulate. Brains after all operate in the perfect simulator and evolution had no reason to avoid expensive to simulate solutions. I would guess that it is rather unlikely, but it is possible since even a single cell chemistry, well even a single organelle chemistry is complex. Simulating processes involving RNA may turn out to prohibitively expensive. Also, I'm sure that theoretically optimal "intelligence program" on silicon processors is vastly different from organic ones. They may share a lot, but the constraints are just so vastly different including the most important ones like energy efficiency or space availability.

>> There may be an issue with running a "brain" program on a non-brain hardware depending on what the program is. That's not impossible! For example, it's easy to find algorithms that a computer can carry out without error that a human mind would really struggle with. Although this is a case of computational resources, rather than the expressive power of the computational apparatus, it's still the case that it's not always possible to find programs that both humans and computers can compute in practice. So it may even be that, while computers can run some programs very efficiently, that humans can't, it's the other way around also and computers can't efficiently run the programs that humans can. In which case of course, either the entire AI enterprise is doomed to failure, or we get lucky and there is some other way to do intelligence that is available to computers but not humans. Who knows!
