A Lenovo Thinkpad X200 is itself a rebadged Wistron Mocha-1, if you want to think of it that way.
Despite what companies like HP/Compaq, Gateway, Dell, Lenovo, etc. want you to think, their products are actually mostly just branded by them, and mainly the work of ODMs such as Compal, Inventec, Pegatron, Quanta, and Wistron. Looking on the motherboard often reveals the true name and manufacturer of the product:
