About MEGA2560 analog pin sequence

Hi,
we knew that the Arduino UNO's pin A0, A1..... also call 14, 15 ....
How about MEGA2560, can its A0, A1...... be called 54, 55 .... accordingly?
Thanks
Adam

          #define PIN_A0   (54)
          #define PIN_A1   (55)
          #define PIN_A2   (56)
          #define PIN_A3   (57)
          #define PIN_A4   (58)

          #define PIN_A15  (69)
          
          
static const uint8_t A0 = PIN_A0;
          static const uint8_t A1 = PIN_A1;
          static const uint8_t A2 = PIN_A2;
