I'm suggesting that the map could show the Crossrail station as

Well, it doesn't yet, and it may be a while before it does. It would
probably be wrong to show the link as an interchange, anyway, as it's much
further than the actual interchange at Canary Wharf. Just because a route's
walkable doesn't make it an interchange.

Archway to Upper Holloway is shown as an interchange (or outerchange) on
the latest tube map, and that's further than the circuitous walk route
available now from Poplar to Crossrail, and much longer than the future
directish route.
