Etymology: "Challengeable" is a straightforward formation: the verb "challenge" with the suffix "-able," which turns a verb into an adjective meaning "capable of being" or "open to" the action named. So a claim that can be contested is challengeable, in the same way a door that can be opened is openable. The base word "challenge" came into Middle English from Old French "chalenge," which in turn descends from Latin "calumnia," meaning false accusation or trickery in a legal dispute. The sense of formally disputing someone's claim or right therefore sits close to the word's roots, and the modern sense of an open invitation to compete is a later extension of that idea. The suffix "-able" comes through Old French from Latin "-abilis," and the Middle English form "chalengeable" shows the pattern was already in place when the adjective was formed. Its meaning has stayed close to the original: something that can be called into question.
