I've checked this - Lenovo document it as being for dock management. It's a software request for the platform to stop using any resources in the dock (such as unmounting filesystems if you have a hard drive in the bay) so that the laptop can be ejected safely. The media eject icon is commonly used on docking stations. The Dell and HP docking stations I have to hand both use it in this way.
