A signal is an abstract concept, it is only information and has no physical manifestation.
A wave is a physical phenomenon, and can be measured in a lab or simulated.
Waves can be used to transmit signals. For example, an electromagnetic wave can be modulated in amplitude to carry an AM signal. This AM-modulated wave is still just a wave. The signal it carries is the interpretation of the wave by a radio receiver. Other types of receivers, for example an FM receiver, will interpret the same wave as carrying no signal.
