Yes you can. If their idea of Islam was correct, it would be the right thing to do. Admit that it isn't correct, and it's wrong.
To be able to see plainly that it's incorrect, you have to make the surprisingly difficult step of admitting that some things are false and there's no reason to believe them. That's a step that all religion wants to stop you taking.
