That's like calling a CRM app "Wiki" because you like the idea of collaborative editing of knowledge (in a world where Wikipedia already exists and is synonymous with wikipedia.org). Like... sure, no one can stop you, but it seems both counterproductive to your own marketing and mildly disrespectful to the other projects that are closer to the original ethos behind the name. It's not that hard to name things uniquely, at least call it "Memexa Code" or something.
