It's not really a question of "getting caught". You will be entering China in Beijing and exiting in Xiamen. While you are in China, you can go wherever you please.
It's also worth warning you that, in the past, PEK has employed strange procedures for pax on one-stop international flights. While you won't get "processed" until you reach Xiamen, you'll need to clear exit customs in BJ (a minor formality). And, unless those guys have cleaned up their act in the past two years since I've dared to take such a flight, you'll be forced to wait in an especially grim gate area on the international side of T2, after security, inside of border patrol... no lounges, minimal food, basically a bus station. (The XMN destination people are not subject to this treatment.)
