Leica M-E Typ 220 has a 18.0MP Full frame (36 x 24 mm ) sized CCD sensor . On the other hand, Leica M10 has a 24.0MP Full frame (35.8 x 23.9 mm ) sized CMOS sensor and features Maestro II processor.
Leica M10's sensor provides 6MP more than Leica M-E Typ 220's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Below you can see the M-E Typ 220 and M10 sensor size comparison.

Sensor Size and Resolution Comparison image of Leica M-E Typ 220 and Leica M10 Cameras
Leica M-E Typ 220 and Leica M10 have almost the same sensor size so none of them has any significant advantage over other in providing control over depth of field when used with same focal length and aperture.
DxOMark Sensor Scores
DxOMark is a benchmark that scientifically assesses image quality of camera sensors. It scores camera sensors for color depth (DXO Portrait), dynamic range (DXO Landscape) and low-light sensitivity (DXO Sports), and also gives them an overall score. Leica M-E Typ 220 and Leica M10 sensors have been tested by DxO and the results show that M10 has a better overall score of 86, 17 points higher compared to M-E Typ 220's score of 69.
