Are there any invalid linux filenames?

If I wanted to create a string which is guaranteed not to represent a filename, I could put one of the following characters in it on Windows:

\ / : * ? | < >

e.g.

this-is-a-filename.png

?this-is-not.png

Is there any way to identify a string as 'not possibly a file' on Linux?

filenames filesystems linux file windows

Technically it's not invalid but files with dash(-) at the beginning of their name will put you in a lot of troubles. It's because it has conflicts with command arguments.
