Yes; rests aren't any different from notes here. There are situations where a dotted quarter is preferred; there are situations where a quarter + an eighth (or the other way around) is the more natural notation.
I don't have a concrete example from existing music, but consider the following example, a 6/8 time signature, where the rhythm is such that (most) measures are divided into two parts of 3 eighth notes. A dotted quarter rest is appropriate if it starts at beat 1 or 4; if it starts at beat 2, a quarter + an eighth is more natural:
X: 1
M: 6/8
K: C
L: 1/8
