Yes. Here is a quick example.
NDSolve[x'[t] == I*x[t] && x[0] == 1, x[t], {t, 0, 2}]
This gives a sensible result, as can be seen visually:
Plot[{Re[soln], Im[soln]}, {t, 0, 1}]
Some methods may require input that is split into explicitly real equations though. This is the case if the input is a DAE system, for example.
