At the moment, not yet. New World crops are beginning to arrive, but the Columbian Exchange IRL took awhile. However, cassava is being planted in Senegambia right about now, and maize is beginning to get its day in the limelight - but what's coming into the Iberian-Maghrebi-West-African world first are the luxury goods. Chili peppers, cacao, allspice, annatto and vanilla? Yeah, they're into those.
Worth noting that many of the first discoverers were spice traders trading in melegueta pepper and false cubeb. Their first impulse is that THE SPICE MUST FLOW. (This is also why the trade with India and Southeast Asia is more lucrative than New World trade. Cinnamon in particular is hugely sought-after in Andalusia.)
The Greek Quran is written in Greek characters; it was written for wealthy Greeks who retained their language. An Arabic script has begun to come together, though, largely because Arabic is such a prestige language.
Regarding the Greek version of the Quran, Islam spread to many different areas with wildly varying languages and all of them read it in the original language. Sure translations existed everywhere but they were always supplemental to the original Arabic.
I doubt in such a scenario a Greek version would ever catch on as a primary religious text.
