Only in the same sense that Moses is not in Tanach either. Nor, for that matter, is Adam, Eve, Noah, Israel, or God. Or Joshua.
Those names are all writen using English characters. Since the Tanach is not written in English characters, none of them appear in the Tanach.
On the other hand, if you're going to suggest in an Anglophone forum that the person created out of dust in Genesis 1 was named something other than "Adam," or that the person who brought the tablets down from Mount Sinai was not named "Moses," you're merely displaying unmitigated ignorance. Similarly, if you suggest that the name "Joshua" appears in the Tanach -- well, Jesus appears in exactly that spot, too. Because Joshua is Jesus. Put down the crack pipe and walk away slowly.
