I don't know which adapter the 2400c requires.  Bu there is no 
problem using the 45W adapter in place of the 36W.  The computer 
simply uses as much power as it can but it won't use more than it's 
supposed to (unless it's faulty).

You can have a problem using a wallwart with an excessive current 
rating as they are not regulated.  This means if you don't  draw 
enough current the voltage is too high.  The Apple laptop power 
adapters are regulated so this isn't a problem.

General rules of thumb for power adapters:

Voltage must match

Polarity must match

AC/DC must match

Connector must match

Current of the power supply must meet or exceed load requirement.  As 
above there can be problems if the current capacity is too high.
