This is my guess, I have no direct knowledge here.
Imperial College London's "Computing" degree is described at https://www.imperial.ac.uk/study/courses/undergraduate/compu... as a program where you can "study the engineering of computer hardware and software alongside the mathematical principles of computing." So it's not just computer science. Compare this to the "Electrical Engineering and Computer Science" (EECS) degrees at MIT, UC Berkeley and other places.
As for changing the name on your CV/resume, whether that's okay depends on the hiring customs for your location and field. That said, I think you're overthinking it. Prestigious schools and employers and people sometimes use unusual names as a mark of distinction. You can get a "Computer Science" degree from any fifth-rate night school, but all the fancy employers you'll presumably be eligible for after graduating should know what a "Computing" degree from Imperial College London is.
