Yes. Anyway you can find to play the notes required for the chord is fine. Gsus4 is:

G (1st)

C (4th)

D (5th)

Any place on the guitar you can play those notes together is a Gsus4!

However, I also encourage you to keep working on the more difficult voicings. The more options you are able to play, the better a guitarist & musician you will be.

Hope that helps!
