I could have sworn I heard keep schedule on a television show where two people were talking informally about making appointments despite last-minute hiccups. But I can't find the phrase anywhere on the internet. "Keep to schedule", or "stay on schedule" seem to be the acceptable forms among a few others. Can I use to keep schedule to mean making all prearranged appointments and going as planned without disruptions?

The phrase keep schedule refers to staying on schedule.
I think it would be fair to say that it is a somewhat dated use.
