Sure, pull the valve covers and look, obvious visual difference. Mechanical lifters will have an adjustment screw and lock nut, the hydraulics will just show a plunger head with a small spiral spring. Also, motor number suffix "H" denotes hydraulic lifters. However, the absence of suffix "H" shouldn't be taken as proof-positive that the engine has mechanical tappets.
