I'm not an expert, but I think it largely depends on your definition of the "routing database". If you store the elevation data in the original grid-based form and you request elevation data on-demand for lat/lon coords without long-term storing of lat/lon + elevation pairs, then I don't really see the two data sources "infecting" one another in legal terms.
Except, of course, if you intend to offer the routing as some kind of high-availability web service which would allow somebody to reconstruct the original elevation data using web scraping. Of course, all of this also depends on you getting the approval/agreement from the CGIAR data owner to use the elevation data for commercial purposes.
