No. Context is crucial. A good rule of thumb is to replace the word ‘Muslim’ in a statement with another minority – how does it look and sound?
Context, however, is not a matter of private intentions, it is public and social: it depends on not only what is being done or said, and who is doing or saying it, but also on the consequences of such doings and sayings.
The risk of Islamophobia is greater when the perpetrator is in a position of authority or influence and has a track record of making inflammatory statements (including politicians, someone writing in a national media outlet or those with significant following on social media).
Similarly (as long established discussions of comparable forms of racism have shown) the risk of Islamophobia will also be different depending on whether the perpetrator identifies as a Muslim, and how they comport themselves towards the expression of Muslimness.
