Can you use a positive plug 4.5v 600mA power adaptor in a device
that calls for a positive plug 4.5v 300mA adaptor without harming the
device? They are both produced by the same company, the only difference
is the mA rating.
 
Yes

Maybe.

Some power adapters are very loosely regulated (e.g., not "stiff") and
only produce their rated output voltage when at or near their rated
load. It's possible that the 600 mA adapter will run well above 4.5 V if
it's only loaded to, say, 200 mA.
