Not quite; a duplexer is typically used where you want to TX and RX simultaneously on quite close frequencies like in a repeater, and a diplexer is more commonly used where you want to TX *or* RX on two different bands. So for combining a VHF and UHF aerial into a dual-band receiver, you'd use a diplexer. For separating the TX and RX frequencies at a repeater, you'd use a duplexer.
