I know of no system agreements that specify a minimum length of 5 cards
for a simple overcall, this is simply common sense.

[Jerry Fusselman]
There some good players who overcall at the one level with a really
good four-card suit. Mike Lawrence, for example. He's a good player,
He talks about in his book, "Overcalls."
I often cringe when a bridge player calls an agreement "common sense."

Or "general knowledge and experience*. In bidding competition problems,
the expert panel is often nearly unanimous in electing to overcall on a 
4 card
suit.
