No. The newer processor will not use the same motherboard.
Pentium 4 sockets were sockets numbers Socket 423 for early Pentium 4's. Then socket 478 for Pentium 4, Pentium 4 Extreme Edition and Celeron and socket T (LGA 775) for Pentium 4, Pentium D dual core, Celeron D and Pentium Extreme Edition.
Yes, there are some "no name" laptop brands that use desktop CPU-s onto their laptop motherboards. I have a laptop of "Vobis" manufacturer and I'm using Pentium 4 , 2.4 GHz, 533 MHz FSB desktop CPU in that machine.
I'm not sure what the pinout is, but you cannot use a laptop processor in a desktop application. Most laptop processors are designed to consume less voltage and produce less heat than there desktop cousins. Only very high-end laptops use desktop processors in them, such as www.alienware.com
The Intel Pentium M is a type of processor that is used in laptops. The M stands for mobile and the Pentium M is designed to use less power and generate less heat than a processor used in a desktop.

pentium 4 more faster
The Dell Dimension 4800 was a brand of desktop that was discontinued in 2007. Some of the features this desktop had were a Pentium 4 Processor and and Intel Extreme Graphis controller. The Dimension series was replaced by the Inspiron line of desktops.
As a whole, the Pentium 4 has a higher maximum performance than a Pentium III. The Pentium III performs the same as or better than Pentium 4 at the same clock speed, but the Pentium 4 has a higher max clock speed (which the Pentium 4 was designed for).
Pentium 4 with HT technology runs at the highest speed.
No, the Pentium 3 and Pentium 4 are not only samples of 2 completely different architectures, but also use a different socket so a change between the 2 on the same motherboard is impossible.
Any AMD Athlon 64, Intel Core 2, or Core i7. Certain Pentium 4 revisions support 64-bit operation, all desktop Pentium Dual-Cores, and all AMD processors using socket AM2 or later.
