I tried it many times to find a solution that didn't corrupt the document and worked as expected:

public static void RemoveAllParagraphs(XWPFTableCell cell, Predicate<string> match = default)
{
    match ??= _ => true;

    var removes = new List<int>();

    for (int i = cell.Paragraphs.Count - 1; i >= 0; i--)
    {
        if (match(cell.Paragraphs[i].ParagraphText))
        {
            removes.Add(i);
        }
    }

    int x = 0;

    if (removes.Count == cell.Paragraphs.Count)
    {
        x = 1;
    }

    for (int i = 0; i < removes.Count - x; i++)
    {
        cell.RemoveParagraph(removes[i]);
    }

    string p0Text = cell.Paragraphs[0].ParagraphText;

    if (cell.Paragraphs.Count == 1 && p0Text != "" && match(p0Text))
    {
        cell.Paragraphs[0].ReplaceText(p0Text, "");
    }
}
