Can only China's calligraphy be called calligraphy?

Calligraphy is the line art of Chinese characters. This kind of line can't be written with a brush.

Such as pencils, pens, ballpoint pens, art pens, bamboo sticks, quill pens, fountain pens, fingers and so on, can all be used to write Chinese characters. Chinese characters written with these tools contain aesthetic line art, which can all be called calligraphy.
