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.
