Can desire without the attachment still lead to suffering? . . YES
The [MahaNidana Sutta][1] says
Ānanda, if one is asked: ‘Are aging and death due to a specific condition?’ one should say: ‘They are.’ If one is asked: ‘Through what condition is there aging and death?’ one should say: ‘With birth as condition there is aging and death.’
“Ānanda, if one is asked: ‘Is birth due to a specific condition?’ one should say: ‘It is.’ If one is asked: ‘Through what condition is there birth?’ one should say: ‘With existence as condition there is birth.’

So aging and death(Suffering) <-- birth <--existence <--clinging (attachment) <--craving (desire) <--feeling <-- contact <-- mentality-materiality <-- consciousness <--mentality-materiality

“Ānanda, if one is asked: ‘Is consciousness due to a specific condition?’ one should say: ‘It is.’ If one is asked: ‘Through what condition is there consciousness?’ one should say: ‘With mentality-materiality as condition there is consciousness.’

Hence consciousness << == >> mentality-materiality (FORM)

“Thus, Ānanda, with mentality-materiality as condition there is consciousness; with consciousness as condition there is mentality-materiality; with mentality-materiality as condition there is contact; with contact as condition there is feeling; with feeling as condition there is craving; with craving as condition there is clinging; with clinging as condition there is existence; with existence as condition there is birth; and with birth as condition, aging and death, sorrow, lamentation, pain, grief, and despair come to be. Such is the origin of this entire mass of suffering.

This is interdependent state.
Now,
Q1). What is desire without the attachment mean?
Q2). In what situations this happen?
Q3). If the interdependency exist that situation?
Q4). Whit are the situations the interdependency not exist?

Anyway if interdependency is, then the suffering may arise.

for example infant child (without attachment-"kama") will suffer future.. [1]: https://suttacentral.net/en/dn15
