Cam you move it outside? Yes, but like @J52 said, don't be tempted to use really large pots coz azaleas have shallow roots and it'd be a waste and when watered this might attract pests and weeds. The shallow roots also help in conserving its soil moisture as well as minimize the soil temp.
Since I am replying to this in January, I guess you're waiting till spring to move it outdoors. And once again, I concur with @Esmay on the dappled shade. Azalea doesn't do well with too much direct sunlight and it won't flower with too much shade.
I'd also like to add that you should use organic mulching. Which provides the azalea with enough nutrients hence you don't have to worry about fertilizing. Once it's gone outdoors, be cautious of leaf spots and petal blight, which is something I've experienced a number of times with my azaleas. Perhaps you might not have to go through the same but just make sure you water them enough.
