By my meaning of the phrase, they have, your nominally Orthodox friend certainly has, and everyone who watches a film does it all the time.

Suspension of disbelief merely means that you withhold your rejection of input as false. In order to understand something at all, you have to temporarily represent it in your mind as true... which is why there are studies that show you can convince people of things by telling them the idea and then distracting them before they have a chance to analyze or reject it. Disbelief is an active, conscious process; belief is the default.

(Which makes sense evolutionarily -- camouflage and deceptive behaviors are perceptual problems, not logical analysis problems. An ability to logically disbelieve probably had to evolve as a defensive weapon against human liars -- it doesn't make much sense to have it until you also have language and imagination.)
