The Australian island state of Tasmania was named after Dutch explorer Abel Tasman. It was not named by Tasman: originally, Tasman named the land Van Diemen's Land, after the Dutch Governor of Batavia, Antony Van Diemen. In 1856, Queen Victoria approved a petition to rename Van Diemen's Land to Tasmania, in honour of its discoverer.

No explorer gave his name to Tasmania. Tasmania was first known as Van Diemen's Land from 1642, when Dutch explorer Abel Tasman discovered it. In 1856, Queen Victoria approved a petition to rename the island of Van Diemen's Land 'Tasmania' in honour of Tasman.

I was a dutch national who became an Australian citizen However the dutch still consider me Dutch. In your case the situation seems a little more extreme and I suggest you contact the Netherlands Consulate for clear advice on this question. You can apply for Dutch citizenship, but as far as I know you will be treated no differently because of the history of your grandfather. Anyone can attempt to apply for Dutch citizenship, but your situation as described in your question does not give you any eligibility.
