No, the sentence “Undoubtedly one of the most popular words in the English language, OK was first used in print in 1839.” is not a sentence fragment. It is a complete sentence with a subject ("OK") and a predicate ("was first used in print in 1839"), and the introductory phrase ("Undoubtedly one of the most popular words in the English language") provides additional information but does not make it a fragment.
