Revised question: Can the Christian God be known, in all meanings of the word (i.e. experience in 'meeting' God, in knowing all about God, in knowing what God expects of you, etc), without the Bible?
This is a better question than the question whether He can EXIST without the Bible, and may be what PB meant. He is God, so of course He didn't have to give us the Bible -- He could have gone on existing without offering us any specific knowledge of Himself.
And of course the idea of a specifically "Christian" God is misleading too. God is God. The Bible is simply His revelation of Himself to humanity.
As to whether He is knowable without the Bible: Only in the most rudimentary sense because of our fallenness which has cut us off from communication with Him (and also because there is a demonic realm which has power on earth thanks to the Fall, which seeks to counterfeit the things of God and lead people away from true knowledge of Him). God's dealings with His chosen people, and their written account of those dealings and His true nature, were given specifically BECAUSE of this inability to know Him rightly. So no, He can't be known in all meanings of the word without the Bible.
