Not quite from what I understand. The KC-135s follow tbe 367 prototype more closely than the 707s. Difference is that the 367 (and KC-135s) are narrower (designed for 5 abreast in economy configuration while the airlines (Pan Am, IIRC) wanted a 6 abreats configuration hence the commercial a/c was widened to becme the 707.
