As long as you get DDR2 SODIMM, and as long as there isn't some motherboard limitation. But I'd say it would be very rare for a DDR2 motherboard to not be able to use at least 8GB.
Sometimes a manufacturer will state there is a limitation, yet if you actually install more than the stated limitation it'll still work anyway.
I have a Sony Vaio YB laptop that I installed 8GB into, even though it says it only supports up to 4GB.
