Depends on the length and diameter of your beer line, but yes.
My preassembled cobra tap has 5 feet of 3/16" beer line. It pours a little on the too-fast side at 15 psi (usually my desired equilibrium; about 2.6 volumes at 43F) and just right at 10. More beer would hit the floor than stay in the glass at 30.
