Is it true that airplane mode reduces smartphone battery drain?

Yes. A reference article on airplane mode states directly that shutting down the device's transmitters reduces power consumption and increases battery life, which settles the claim. Two peer-reviewed studies on smartphone power add partial support by showing that cellular, WiFi and GNSS radio activity is a major source of battery drain, though neither tested airplane mode itself.
