AFAIK no. It won't work anyway as all modules used by your program 
should be compiled by the same compiler version (your program depends on 
LCL and Lazarus depends on it too, hence LCL, Lazarus and your program 
need the same compiler version).

IMO the best option here is to use 2.2.0 for production software. 2.2.3 
can be used too, but there can be some unexpected glitches. Also you can 
try 2.2.2rc1. It is newer than 2.2.0 and should be more stable than 2.2.3.

BTW if Lazarus doesn't compile with 2.2.0 then you have found a bug.
