As long as voltages match and you have the proper amperage for the device, plug and receptacle you can do what you are describing. One thing to be aware of is that in many jurisdictions a 4 wire setup is required for a dryer and in some only a 3 wire is required, especially if it is an old installation.That means that on the 4 wire setup you will have 2 phase legs or hot wires, a neutral and a ground. For a 220V compressor the neutral is not needed, only the hot wires and the ground. If you are doing this yourself just be careful and make sure you have it wired properly before you close the breaker. If you aren't sure ask us.
