Unless he carries a official document bearing both names and is able to convince them, but i'd say much better to just resolve it b4 going to airport.
However, small erros like speeing Cheng instead of Cheung should be okay.
Agreed, the US would be extremely risky. If it was within Asia, he could take a chance, but better safe than sorry, I say. I did get my passport amended to include "Thomas" to avoid mishaps like this again.
