The term "amateur" is often applied to people who have obtained a license
to use radio equipment for communications. Is this term inclusive of
those who don't obtain a license but use receivers for various uses?
I have been looking into design of receivers in the LF to ELF frequency
ranges. Is this part of "amateur" radio?

How appropriate that you should confuse, "license" with, "licence"!
