The USB image uses a bare BSDlabel, aka "dangerously dedicated", meaning there is no MBR at all. Some versions of Thinkpad firmware had strange misconceptions about disk formats. A CD could boot fine, being a more common format. Make certain the Thinkpad firmware is the latest version, and the USB image might work. Some work with gpart and dd might be able to convert the USB image to an MBR/BSDlabel format which would boot. Or the problem might not be related to the bare BSDlabel, but that it works on everything but the Thinkpad make it a good guess.
