These modules are made to provide a virtual UART connection wirelessly. So the answer to your question is yes.
If you want to use the Arduinos to just be able to use these modules I would suggest using an Arduino Leonardo because there you have the virtual serial interface on the USB and a hardware serial interface in addition. Software emulation (especially that crippled SoftwareSerial) will never work as reliable as a hardware serial interface and are very limited in the available baud rates.
