Using if/when in a real condition in the past with could in a main clause

Hello, I have a question about using if/when in a sentence with modal verb "could".
I have Michael Swan's "Practical English Usage" 2nd edition.
In the section that I've made a screenshot of the author says that we can use "could" when we want to say something about what is/was common or typical.
Is it possible to change "if" to "when" in the sentence that I pointed at with a red arrow so it will be like this "It could be quite frightening when you were alone in our big old house"?
I'm asking this because I think this sentence is "an open/real condition in the past" and means that "something sometimes happened and can be rephrased with "when" instead of "if".
Thank you beforehand for your answers.
