You put the word-boundary \b and the negative lookahead inside the character class. This is what I would do and set ignore case:

^(?:[B-MP-ZåäöÅÄÖ\._]|\bA(?!ND\b)|\bN(?!OT\b)|\bO(?![KR]\b))*$

1 & 2
Swedih alphabet (includes alphabet from the english language, and those you mentioned in your regex), numbers and underscore: [\wåäöÅÄÖ]

3
Add dot...: [\wåäöÅÄÖ.]

4
No strange characters in the above character class

5
No white space allowed in the above character class

6
Specific words through a negative lookahead and adding anchors and quantifiers and flag:

@"^(?:(?!\b(?:AND|O[RK]|NOT)\b)[\wåäöÅÄÖ.])*$", RegexOptions.IgnoreCase
