The Treaty of Torsedillas was intended to prevent clashed between Spanish and Portuguese explorers and conquistadores as they carved up these mysterious new lands reeking of promise (and gold. Lots of gold). In the end, it failed repeatedly at this for a variety of reasons, partly to do with the Iberian Union upsetting matters, but mainly because the Pope's line was drawn when knowledge of the New World was still in its infancy, and only gave a sliver of Brazil to Portugal. In the end, as we know, Portugal expanded far past this to produce the huge Brazil we all know and love, clashing repeatedly with Spain along the way.
But what if the Treaty had been drawn up differently? We can't expect the Pope just to move the line to the west when it was unknown how large the New World might be. But what if the line had been one of latitude rather than longitude? (A justification for this might be the fact that latitude was much, much easier to calculate than longitude at that time, meaning the other nation would have less excuse for its people turning up on the wrong side of the line).
Say the Equator, or to favour Spain a bit more, maybe something like 15º South. Everything north of this Spanish, everything south Portuguese. Plausible? (A knock-on effect might be for Spain to have a go at colonising North America north of Florida; they did briefly attempt this with an abortive fort in South Carolina in the 16th century in OTL).
