Yes. It's just a hero name, and most non-Saitama stuff in the series is fairly steady.
I don't think his speed is even much different than Speed of Sound Super Sonic (or at the least, I don't know which is faster)- and it's even noted how Lightspeed pairs well with another strength-based hero who's likely not in the mach speeds.
What exactly did his page show?
