Rechargable batteries tend to have a lower voltage than non-rechargable,
so the voltage difference might cause trouble. My guess is the "Use
alkaline batteries only" is there because the manufacturer knows the
device likes to eat batteries for breakfast, lunch, and dinner.

However, the terminal usable voltage of an alkaline will be very similar
to that of a Ni-Cad, etc.

I discovered recently that Duracell quote battery lifetime to 50% of initial
voltage ! Any rechargeable will be far better.
