Could you learn from a Sefer Torah Shekasvo Min?
BTW, the name Nittul is a play on what it was obviously referred to by the christians, Nettle, which means birth in Latin.
The name Nittul suggest another reason not to learn. The Gemara says regarding Trayfos, Kol Hayesser Kinatul Dami, what is extra is as if it is missing — and renders the animal a Traifa. Now, since they added to the Torah, and thereby ruined the while concept of torah, we don’t learn that night to show that adding is taking away.
