sure...

It may be easier to pass a pointer to the Serial object into the class, for example:

class Context{
  public:
    Context(HardwareSerial* serial){
      stream = serial;
    }

    void send(const char* mssg){
      stream->print(mssg);
    }
    
  private:
    Stream* stream;
};

Context myInstance(&Serial);

void setup() 
{
  Serial.begin(9600);
  myInstance.send("Testing, 1, 2, 3");
}

void loop() {
  // put your main code here, to run repeatedly:

}
