Yes. Runners may go once a fielder has touched the ball (not judged from the catch).

Same ruling in all codes.

Here is the ruling in all codes--

2019 NFHS rule 8

SECTION 2 TOUCHING, OCCUPYING AND RETURNING TO A BASE

ART. 4 . . . If a fair or foul batted ball is caught, other than a foul tip, each base runner shall touch his base after the batted ball has touched a fielder. (See 8-4-1c for fielder intentionally dropping the ball and 8-4-2i for runner being put out.)

PENALTY (Arts. 1-5): For failure to touch a base (advancing and returning), or failure to tag up as soon as the ball is touched on a caught fly ball, the runner may be called out if an appeal is made by the defensive team…

2019 OBR Definitions of Terms CATCH

(Catch) Comment: A catch is legal if the ball is finally held by any fielder, even though juggled, or held by another fielder before it touches the ground. Runners may leave their bases the instant the first fielder touches the ball…

The highlighted phrase is also found in the Comment following 2019 rule 5.09(a). OBR has had this rule since 1920.

The applicable rule in the NCAA is 8-6a-1.
