I'm thinking you got things a little mixed up. Anything flying has a
Max Q, Skylon included. Skylon may not reach it but it still has one.

ncidentally, Skylon doesn't have a max dynamic pressure like rockets
do. It flies up the constant dynamic pressure line, gaining speed as
the air thins out. If I remember correctly, it was about half an
atmosphere.
