Yes, and it is not especially difficult. There are excellent, idiot-proof instructions on the web.
My one piece of additional advice would be to used leaded solder, as its melting point is lower than that of leadless solder. Also use a low-wattage soldering iron. By such means, you are less likely to ruin the components that get re-used, and less likely to compromise the brand new cells, through overheating. You will also not die of lead poisoning from such a small piece of work.
I am no electronics whiz, but I have re-packed an eMate battery with excellent results, and plan soon to do my MP2100, as I recently acquired a spent rechargeable battery for it. For over a decade, however I have used Alkalines (my Newton is still used daily), so it will be interesting to see if and how this changes my experience of using the fabulous little machine.
