Huh? Of course it is. A star is, so long as you don’t draw it out of two interlocking triangles, or construct it from 5 straight lines, and leave the internal parts of those lines intact. A crescent just…is. Unless you’re trying to claim the stars that sometimes appear with a crescent (e.g. on some Islamic country’s flags) are a part of the crescent itself.

Wait, you don’t mean the line has to be straight? If that’s what you mean, I’m fairly sure the internal lines in the post are only there as construction. The section of the triangle that’s inside the smaller circle is just there to show dimensions, so it’s drawn (slightly) thinner than the external lines
