> 41.2% is not the majority…

Yes it is if all other numbers are smaller.

No. Majority is a subset of a set consisting of more than half of the set's elements.

Google search for "majority":

  noun
  1. the greater number.
     "in the majority of cases all will go smoothly"

Also, from your link:

> use of this term is inconsistent as it sometimes refers to a mere plurality (as opposed to an absolute majority)

They are both majorities, except one is absolute (more than 50%) and the other one isn't (more than anyone else, but not over 50%).
