That photo is definitely big enough to tell...

Main things are:
1/ Turbine housing is 'squarer' than the S5
2/ Turbo to Manifold flange bolt pattern is an odd shape, S5 is pretty much a rectangle.

Other ways that aren't shown in the pic:
3/ S4 has a straight actuator rod, S5 has a bent one
4/ S4 has one wastegate hole, S5 has two.

Can't think of any other ways off the top of my head, but these are just the easiest ways!
