As EMBQA says, the KC-135 is not quite the 707, although they're close cousins. Incidentally, the KC-135 (which is a USAF designation) was called Boeing Model 717, which explains the gap between 707 and 727. The designation was purely internal.
707, 727, 737, 757 share the same cabin width, but the fuselages have different cross sections. The KC-135 is a mite narrower.

Those must have looked veeery interesting! Funny that they were toying with a concept similar to the A380 (4 engined full double decker) that long ago...

Quoting JAM747 (Thread starter): How many planes apart from tankers were derived from the Boeing 707? I know the 737 and 727 has the same nose but is that the only commonality? Does the 757 share any 707 genes
Well let me get a good list started. Remember first of all that the 707 is actually a derivitive aircraft. The 367-80 was the first. The B-47 taught Boeing Engineers a lot about desigining high speed wings but I don't htink I would call it a grandfather.

You can go a little further than that. All of Boeings airplanes, from the B-367-80 (not counting any MD design) have a common cockpit design. Yes, the cockpits have been updated as avionics and navigation equipment improved, and the Navigator/FE was removed, but it is still basicly the same.
The list includes:
C/KC-135 and derivitives (B-717-100/200)
B-707-100/200/300/400/700 (+ F and all militery derivitives)
B-727-100/200 + F
B-737 (all derivitives + F + military versions)
B-747-100/200/300/400/E-4/VC-25 + F
B-757-200/300 + F
B-767-200/300/400 (+ F and all military versions)
B-777-200/300 (all versions + F)
