Yes, an inductor in series with a constant current source is like a
capacitor across a constant voltage source.  However, both could interfere
with the feedback loop of the sources if they are active sources, possibly
causing oscillations and other undesired effects.  Usually the capacitor
accross the output of an active voltage source is to take care of the
frequencies those that the active circuit can handle.  You often see specs
for the maximum allowed capacitive load for voltage regulators.
