Can I upgrade this processor?

Hey,

I’ve got this Fujitsu Siemens Amilo Notebook. It has an Intel Pentium M Centrino Mobile 1.5GHz processor. I searched on the internet and found that it’s a 478-pinned processor. Can it be upgraded to an Intel Celeron D (3.01GHz, 478-pin) or an Intel Pentium 4 (2.4GHz, 478-pin)?

Thanks in advance
