Linked? I'm not sure that a single word gives that concept merit. I know that a part of the standard IQ test is to give two words and ask how they are similar. It starts easily, like bike and car (wheeled, mode of transportation, etc) and get progressively harder. If one tries, one should be able to come up with a commonality between any two concepts.
