Can I mod out stuff from the Chronicle?

Is there a way to get rid of the "custom" posts in the chronicle?
The things that automatically adds in, about double moons, floods and such things, so that I only see the things that "actually" happens?

I can see that there is a file Chronicle_events, that calls the 00_on_actions, and in here there is following:
# Fires at the end of each year if the chronicle is empty
on_create_chronicle_if_empty = {
random_events = {
100 = CM.10500
100 = CM.10502
100 = CM.10504
100 = CM.10506
100 = CM.10507
100 = CM.10509
100 = CM.10511
100 = CM.10513
100 = CM.10515
100 = CM.10517
100 = CM.10519
100 = CM.10521
100 = CM.10523
100 = CM.10525
100 = CM.10527
100 = CM.10529
}
}

Can I just delete all that, and then get rid of the posts?
