A reader of the Scriptures of course should be open to many suggestions with regard to how to interpret a particular passage. But that reader should also understand that Johannine literature is tricky; the theology is peculiar (the only sustained "high christology" in the NT), and so is the vocabulary that supports it.

"Truth," as in John 18.37, as quoted in the article, followed by Pilate's "What is truth?" in the next verse, and even more clearly in "And you will know the truth, and the truth will make you free," 8.32, refers to the Johannine community's particular insight regarding Jesus (and not at first shared by other Christian communities of the first century), that he is the Word of God who was with God in the beginning and is come into the world.

If a reader wishes to apply these verses to other, more generally accepted meanings of "truth," he/she is free to do so, but is advised to proceed with caution.
