The short answer is yes.

Do to the nonuse I would suggest sanding lightly just to open the grain. Wipe out the dust with a damp rag or sponge. Do NOT put anything on the wood unless it is distilled water. I would suggest not putting anything on it at all and just use the bowl of water for a couple of weeks. Go slow, there is obviously no hurry if it hasn't been used for a couple of years, so do it slowly and avoid the urge to rush it in a day or two.

Now, if the humi has been stored where it was to dry, you may have to wipe the seals down a couple of times to allow them to swell enough to do their job, but everything else should be fine in a couple of weeks.

After that, slowly add some sticks and verify the humidity. You should be good to go.
