Of course.

(file-name-sans-extension (buffer-name))

A quick way to discover commands is to type:

 C-h f <first-few-letters> TAB

 (C-h = Ctrl h)

so, to find out about file-* commands type:

 C-h f file TAB

and keep pressing TAB to cycle through the numerous results in the
pop-up window.

Add some more letters and type TAB again to narrow your search and when
you've found a command you're interested in type RET.

There's also 'M-x apropos'.
(M-x = Alt-x or ESC-x)

Type 'C-h f apropos RET' to learn about the 'apropos' command.
