We have the tags node and tezos-node on Tezos. Both tags refer to a node in Tezos. Because they mean exactly the same thing, I think we should make one a synonym of the other. It would probably be better to make tezos-node the one remapped to node because we really don't need to prefix "node" with "tezos". The name of the site makes it pretty clear it's referring to a Tezos node, and if there's confusion we can make a tag wiki.
