"Hackintosh" and "Laptop" don't go well together. Regardless of the type of laptop. A certain model HP laptop is a small exception, but it's not 100% perfect.

From my own personal experience running a Hackintosh on a desktop PC I built myself (using community recommended and tested compatible components), I can say that a desktop Hackintosh can be very stable.

However, with a laptop you will be making compromises. The exact compromises vary from laptop to laptop. Usually these will include Wifi, battery life and general power management stuff (hibernate, sleep, etc) and possibly more. For a Thinkpad specifically, I do know that you'll end up needing to use a separate Wifi adapter as the built in one will not work with OS X.

To be honest, since you seem dead-set on a Thinkpad (and I don't blame you, I love them myself) I don't know what to suggest, aside from "don't bother" which you probably won't find too helpful. I would just caution you, don't set your expectations too high, regardless of what you may read on tonymacx86 or wherever else. As runjake said, people have widely varying definitions of stable.
