Denied it? He didn't even mention it. Feel free to read it for yourself: Memoir of Roger Brooke Taney, LL.D.: Chief Justice of the Supreme Court of the United States
It's actually a pretty interesting read. Taney apologized for almost nothing, so if he really thought Lincoln was going to arrest him I have a hard time believing he would have left that part out.
Do tell where he did so.
Taney approached Samuel Tyler some time in 1862 to write his memoires. It's all there in the book.
Also...why do you suppose several other sources - 3 of them - say Lincoln signed the arrest warrant for Chief Justice Taney?
Why do you suppose that several other sources - three biographies and one autobiography - have nothing to say on any arrest warrant claims?
Taney was silent on the matter in his memoirs.
Silence does not prove the negative as you are trying to claim.

Why do you not read the link I have already posted? It answered your question directly. I even copied the text here for you to read. You obviously did not.
