This is from the FAQs:
For the purposes of this jam, a one-page RPG is a tabletop roleplaying game (TTRPG) where the rules fit onto a single page of letter/A4-sized paper. For the purposes of the jam, a TTRPG could include everything from strategic, combat-oriented adventure games; to collaborative and GM-less story games. The aim of this jam is for people to experiment with different designs.
If it falls under that, I would say go for it.
Hope that helps!
