If not, are they interchangeable?

They are both rechargeable batteries. The NiCd battery (nickle cadmium is good for about 1,000 charge-discharge cycles. Due to the cadmium, it requires special disposal.
The NiMH (nickle metal hydride) can hold approximately 50% more power than the NiCd battery and so last longer between charges. The NiMH battery is good for about 300 - 350 charge-discharge cycles. Since it has no cadmium it doesn't require special disposal.
Each battery needs an appropriate charger. There are chargers that can handle both types of batteries, called a smart charger.
Either battery can be used interchangeably with a standard alkaline cell of the same type, ie AA or AAA, etc.

NiMH is an improved version of rechargeable batteries, they don't have the memory problem that NiCd's do. The only thing is you will need a special battery charger for them.
I've used both types in radio control cars and the NiMH don't have to be totally discharged to prevent a memory to built up in them, they will give you a full charge every time.
NiMH will cost more also.

Batteries of the same designation (AA, AAA, C, D, etc.) are interchangeable in the devices they power, but the different chemical compositions determine current drain rate, longevity, etc.
Ni-Cd batteries have Nickel and Cadmium elements and don't generally last as long as Ni-MH (Nickel Metal Hydride) batteries. There is also less or no memory effect with NiMH batteries, in that if you discharge and recharge the battery less than completely, the battery will remember a less-than-full state and deliver less runtime current.

NiCd batteries are typically heavier and used in things like power tools. NiMH are lighter and used in electronics where the power draw is longer and steadier.
An important thing to note is that NiCd batteries contain heavy metals which are bad for the environment. They must be disposed of properly!

They should be interchangeable if they are the same size and voltage. NiMH batteries are better than Ni-Cd, offering a more consistent voltage across their life and don't suffer from memory effects of Ni-Cd. Which means they will give a longer life per charge and they don't gradually get weaker and weaker, they put out almost full voltage till they die and need charging. They do require a special charger, so you can't use them in a Ni-Cd charger

No, they are totally different.
NiCd - NiCAD battery
NiMH - Nickle Metal Hydride Battery
The rechargers required for them are different.
Unless the batteries are configured for use as "standard" batteries - AA, AAA, C, D, 9 volt, etc. - the batteries are not interchangable because there is a special circuit in use in the device for regulating the charge deletion from the battery and recharging.
