Partially. If you avoid the class names that are used at boot time, you should be fine. But bootstrap defines some tag-specific styles, such as
a {
background-color: transparent
}
You can get around this by specifying a style like this:
.without-bootstrap > a {
}
Example:
.wrapper {
background-color:#f00;
}
.no-bootstrap > a {
background-color:#fff;
}
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.2/css/bootstrap.min.css" rel="stylesheet"/>
<div class="wrapper">
<div class="no-bootstrap">
<a href="#"> No Bootstrap</a>
<div class="bootstrap">
<a href="#"> With Bootstrap</a>
</div>
</div>
</div>
