>>  could this be a reason

Probably not.  More likely dust in the system or fan not working properly.

But describe the problem a little better.  

How long does it take to heat up and how do you know it is a heat problem?

like previous poster stated - don't think it's a battery issue.  You can run off adapter fine.  Remove the fan unit / apply new thermal grease to heatsink.

Is it just shutting down after some time?  Does your machine feel hot to touch?

The lack of a battery would not be the reason for overheating.
To ensure that it is overheating you can run this program to monitor the CPU temp.
http://www.cpuid.com/softwares/hwmonitor.html
it will also tell you the model of CPU and from there you can research what temps it should be running at. Compare that to the actual temps in the monitoring program.
Something you can do is blow canned air(actually freon) through the vents to remove dust build up on the cooling fins.

If that doesn't help then you may have to dismantle the laptop and apply new heatsink paste to the CPU. This model requires a full removal of the motherboard to access the heatsink so if you are not familiar with this type of procedure it should be done by a service tech.
Here is the service manual to help guide the dis-assembly of the laptop.

i know of no laptops that have problems running from AC alone

i would start by verifying that all fans run, and the system is cleaned from dust, as said by sparkmaker
for monitoring the cpu temp, i recommend speeedfan:  http://www.almico.com/speedfan.php
