Absolutely.

If you define impedance as voltage/current, then you run into great
difficulties if you try to do it in the time domain.  In general, with any
complex impedance, v(t)/i(t) has singularities (undefined, infinite).

I consider impedance = v(s)/i(s) or v(f)/i(f), which makes it a strictly
frequency domain parameter.
