As part of Ubuntu certification if an altered image is used then we supply that to the OEM. So Lenovo was given an image for the X140e - that's why the Cert page specifies a vendor image.
You have to request that image from the manufacturer. Probably through their support process. I don't know how it works for Lenovo.
The reason this happens is because hardware revisions and Linux kernel, and OS releases (e.g Ubuntu) are not in sync with each other. Eventually the changes for each hardware certification flows into the Ubuntu LTS release for that time. So, they probably went into 12.04.2 in this case. But, in some rare cases it's not possible for all changes to be taken - so generally it's best to get the preinstall image.
