Of course you could. The old bed warmers that they put hot coals in were made of metal

It would have some drawbacks however:

  1. Compared to metals, the temperature of the water in the hot water bottle is limited to a comparatively safe range by the physical properties of water, it will boil off at 212 °F./100 °C. On the other hand you can get metals white hot- enough to burn right through the material of your bed - and they will still be solid.
  2. Water has a higher heat capacity than metals per unit mass and per unit volume so it can supply more heat without having to start out as hot as the metal would have to in order to supply the same amount of heat.
  3. Because it has a higher heat capacity it would also take less water to warm the bed than metal.
  4. An empty hot water bottle is easier to store than a chunk of metal - and a lot cheaper.

You could, but you would have the following problems; it is for these reasons that a hot water bottle is used:* You could easily get burned, because metal is a good heat conductor, and because it is easy to accidentally get the metal way too hot.

* If you keep the metal at a reasonable temperature, it won't last long; first because it would have to be way cooler than the 100 °C or so that you can heat water to, and second, because metal has less heat capacity than water.
