### No, you can not.

As quoted, the *Teleport* spell allows to teleport a single object instead of creatures:
> [...], or a single object that you can see within range, to a destination you select. If you target an object, it must be able to fit entirely inside a 10-foot cube, and it can't be held or carried by an unwilling creature. 

Although the globe created by the *Freezing Sphere* spell satisfies the dimension requirement and it is carried by a willing creature (the caster themself), it is not an object, hence it is not a valid target for the *Teleport*. Indeed, when a spell creates an object (in game terms) the description specifies that: see for example [*Arcane Hand*][1] (emphasis mine):
> **The hand is an object** that has AC 20 and hit points equal to your hit point maximum.

As a DM probably I would allow this, mainly for the following reasons:
- This is a creative idea of combining spells.
- The caster is using 2 high level slots; moreover, until level 20 there is just one 7th level slot available.

Anyway, I would put some caveats:
 - An INT(Arcana) check for successfully combining this two spell, beside using the table in the *Teleport* spell. The DC should be quite high, since a caster with 7th level slots usually have at least +10 in INT(Arcana) checks.
- If the check is successful but not higher than DC+5 (e.g. the DC is 22 and the caster rolls 24), the caster suffer from at least one exhaustion level. This is inspired by consequences of Saving Throws that fail by 5 or more, like the one triggered by a [Drow's][2] Hand Crossbow Attack.
