Yes, you can use "whether" instead of "if" here. In informal speaking, "whether" and "if" are often used interchangeably. However, "if" is more common and informal while "whether" is a little bit more formal. If a sentence is conditional and only presents one option, it is usually okay to use "whether" and "if" interchangeably. However, if a conditional sentence presents two alternatives, you should always use "whether". Ex: I don't know if she's going to the party. Ex: He didn't say whether or not he is interested in the job. Ex: Whether rain or shine, we will still have the soccer game.
