The IGW explanation was misleading, when i say it often increases range thats usually in combination with a tank increase. But yeh the higher MTOW means it can carry more fuel thus go further. IIRC Some planes cant fill the tanks to the brim and carry a realistic payload similtaneously so occasionally a MTOW alone can boost the range slightly at certain payloads, but its usually a combination of the two.
Experts, Feel free to bash me if anything is wrong.
