You can download all Somatic mutations from the TCGA portal as pointed out by Chris Miller.
I would want to contradict what Chris said though. The TCGA MAF, as far as I have understood, contain all Somatic mut. And that would include any somatic mut. which were non-coding as well. What you wont get without a licence are the Germline calls.
As an e.g. here is a screenshot of the types of mut. present in the MAF file for melanoma (SKCM) samples -
So, **ALL** somatic, including non-coding as well. Though I have not worked with the AML cohort, I presume that this (coding as well as non-coding somatic mut. present) must be the situation for most of the MAFs available from TCGA, if not all.
