is there a better way to write this in Kotlin? I'm not trying to solve anything real, just playing around

fun File.asSequence(): Sequence<String> {
    val reader = this.bufferedReader()
    return sequence {
        while (true) {
            yield(reader.readLine() ?: break)
        }
    }
}

and is combining scopes frown upon? for example

fun File.asSequence2(): Sequence<String> = this.bufferedReader().let {
  // now sequence { } allows me to have `it` for the reader and `this` for the sequence
}

(ignore the fact that that first line in particular got really long)

You could do the same thing with the useLines extension function from the stdlib: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.io/java.io.-file/use-lines.html
As for your 2nd question, I see nothing bad in mixing it and this as long as it is still obvious which refers to what.
