We see that a retaining wall as in the picture is not carried safely enough. But there is already something strange about this question. The retaining wall calculation varies according to the soil parameters. There is no information about the ground. Given can be height and ground values. The rest should be desired. But as far as I can see, the foundation thickness, shoe width and wall thickness are within the given range. There is nothing left to the desired part here. Just a "yes it can or can't" answer. However, thousands of kinds of walls of the same dimensions can be made from the shape I have given. For example, if a tooth is made on the base, all values will be turned upside down. Or even the fact that the 2m foundation width you mentioned is partially centered on the back, front or as in the picture changes so much. You must be aware of these.
