Hi,
In BlendLuxCore(2.0rc1), I cannot change(link) another node tree to the material in node editor (blender2.79b).

Yes, each material has exactly one node tree, just like in Cycles.
Why would you want to change it?

It seems a fake user is created for each node tree, but not for material.
So If I, remove a material from an object (save & reopen file).
The material is removed and node tree is not removed as expected.
But I can't find a way to delete nodetree (or assign to another material) from node editor.

That's true.
But I think the solution is to somehow find and delete these orphaned node trees.
I added a note here:

Volume nodes have same issue.
Currently Image & volume nodes can be unlinked manually.
But material node tree can't be removed, As we can't even select them in node editor
.
Thanks for looking into the problem.

You can see them if you click the "pin" button the node editor.
Then you can also manually flag it for deletion with Shift click on X.
