A computer is something that computes things... An iPad, iPhone, calculator are all “computers” ..
Can an iPad be a main computer for someone? Likely some users, yes... IMO an iPad can’t be a main computer for me as it just sucks so bad at “work” tasks and can’t replace a computer with a full blown operating system.
The question should almost be: “can iOS be used as a MacOS/Windows OS replacement?” ... IMO, the answer to that is no.
