Agreed. It's such a unique name for a classic algorithm and is so thoroughly established in symbolic pattern matching for production systems that I'd seriously recommend against adopting it for any other purpose in CS.
Yes, it is, but this is not necessarily a bad thing.
For a detailed explanation, see Pieter's keynote on EuroSciPy 2015 [0], where he answers a similar question around 19:45; however, his entire talk is worth watching because it sums up very well the ideas behind the C4 process.
